Notes on the cars:
- McLaren M16C  (Johnny Rutherford): New for McLaren Cars to be driven by Johnny Rutherford as the #7 Gulf entry in 1973. He used this car at the Indy 500 but may have used M16C/2 (or even M16C/4) at other races that season. Raced again by Rutherford in 1974 as the #3 car, winning the Indy 500, but he used another M16C at short track events that year. This car then became Rutherford's short-track car in 1975 and 1976. Sold to George Walther to be Salt Walther #33 backup car at Indy in 1977 but how it was used that season is unknown. Entered by Walther at the 1978 Indy 500 as the #34 for Graham McRae but he was bumped. Sold by Walther to Rick Carroll (Jensen Beach, FL) and restored. Sold by Carroll's estate in 1990 via Sotherby's Palm Springs Auction for $495,000 to Patrick S. Ryan (Montgomery, AL). Loaned by Ryan to the IMS Museum but also attended various concours events while owned by Ryan. Repainted by Paintergeek Paintworks (Indianapolis, IN) in May 2013. Sold by Ryan through RM Auctions at Monterey in August 2013 for $3,250,000 to web entrepreneur Bill Oesterle (Indianapolis, IN).
- Eagle 72  (Billy Vukovich): One of two 1972 Eagles bought new by Jerry O'Connell's Sugaripe Prune team and raced by Billy Vukovich as the #3 entry in 1972. As the later history of 7207 is known from an invoice, and as the cars have distinct differences that can be seen in photographs, 7204 can be safely identified as Vukovich's 1972 Indy 500 car, after which it swapped roles with 7207 and became his short track car. It remained his short track car in 1973, and is then believed to have raced just twice in 1974. Sold to Donald Mergard and very probably the car raced by Bob Harkey as Mergard Racing's #42 entry at Michigan late that season. Retained by Mergard for another six seasons, racing as the #42 with numerous drivers and sponsors. In 1981, this car appears to have become Tom Frantz' #71 entry for Bob Frey. Subsequent history unknown.
- Eagle 73  (Gordon Johncock): New for Jerry Grant to race at the 1973 Indy 500 as AAR's #48 Olsonite Eagle. Grant was not entered at the Pocono 500 and the car was sold to Patrick Racing prior to that race. It was raced by Gordy Johncock for the rest of the season as his Indy-winning car was wrecked at Pocono. Raced by teammate Wally Dallenbach in the early races of 1974, then brought to the Indy 500 to replace a '74 car damaged by Johncock in practice. Raced by Johncock at Indy and at Milwaukee in June, and believed to have been his short track car for the rest of the year. Then to Lee Elkins and entered as the #83 McNamara Eagle for Bill Puterbaugh at Indy and at Pocono in 1975, qualifying for both. Retained for the 500-mile races 1976, when Puterbaugh qualified for the Indy 500 and Ontario, and also in 1977 when, now as the #16 entry, he again qualified for the Indy 500. Immediately after qualifying, the car was acquired by George Walther who wanted to put son Salt into it but after an uproar, Puterbaugh drove it in the race. Then from Walther to Bob Olmstead who fitted a Volker V12 engine for Indy 1978 but did not get the car on track. The car was stored until after Olmstead's death, and was sold to Bill Simpson in the early 1990s. It was restored as a show car for Simpson by Wayne Leary and put on display in North Carolina to represent the Eagle that Simpson had raced at Indy. Sold around 2013 to Jeff Urwin (New York, NY).
- McLaren M16C/D  (David Hobbs): New in 1974 for McLaren Cars as a M16C/D for David Hobbs to drive at the 1974 Indy 500 as the #73 Carling Black Label entry. Sold to George Walther by early July for Salt Walther to drive and used as his main #77 car at the Indy 500 in 1975, 1976 and 1977. Walther had other McLarens during this time and he is likely to have used those on short tracks. Sold with M16C/2 to Jerry Karl for 1978 and entered as his #88 Offy car with Frank Fiore as chief mechanic and a #89 RasCar/Atlanta as his backup. How this car was used later is currently unclear. Sold with M16C/2 to Chuck Haines (St Louis, MO) and stored for some years, before undergoing a complete restoration in 2015. Appeared at the Historic Indycar Exhibition in May 2016 in immaculate Carling livery. To Rob Dyson (Millbrook, NY) of Dyson Racing c2017.
- Eagle 72  (Jim McElreath): New to Don Gerhardt to replace chassis 7206 destroyed in Jim Malloy's fatal accident at the 1972 Indy 500. Raced by Johnny Rutherford as the #18 Thermo King Special entry for the latter half of 1972. Retained for 1973 when Mike Hiss took over as team driver but Gerhardt had also acquired chassis 7216, and 7209 was used mainly on short tracks that year. Jim McElreath took over the Gerhardt drive in 1974 and used both 7209 and 7216 at the 1974 Indy 500, racing 7209. Gary Bettenhausen rejoined Gerhardt for 1975 and raced 7209 at the Indy 500 and at Pocono, with 7216 now being used on short tracks. For 1976, Bettenhausen used 7216 at the Indy 500, and 7209 was allocated to Eddie Miller but he destroyed the car in a heavy accident during practice. The remains sat at a body shop in Fresno, CA for a long time, before they were acquired by John Mueller for parts to aid in his restoration of 7228. He scrapped what he did not need, but part of the footbox together with the chassis plate were sent to Jacques Dresang as a souvenir.
- Eagle 72 (Duane "Pancho" Carter): One of two 1972 Eagles bought by Robert L. 'Bob' Fletcher and chief crew Clint Brawner for Fletcher's new Cobre Firestone team in 1973. This car arrived in time for the race at Texas World Speedway at the start of April so is likely to be chassis 7214. Entered at TWS as the #21 entry for Jimmy Caruthers, and it is assumed that this was the same #21 entered for him at Trenton and at the Indy 500. After Art Pollard's accident in the sister car, this was Fletcher's only remaining 1972 car and it was driven by Caruthers for the rest of 1973, then by Duane "Pancho" Carter at the Indy 500 in 1974. It is likely to be the car raced by Carter later in the season but he might have been allocated one of the team's 1974 Eagles. The car was renumbered #55 for 1975 and entered for Lee Kunzman at Ontario, where he finished third in his heat and fourth in the final. Entered also at the Indy 500 but Kunzman did not qualify. The car was not needed again but remained with the team as a show car. It was photographed in Frosty Acres livery, which cannot be earlier than 1979. Subsequent history unknown.
- Kenyon-Coyote (Bob Harkey): The history of this 1970 Coyote chassis is unknown before July 1971. After Mel Kenyon's Kuzma was wrecked during the 1971 Indy 500, Mel and Don Kenyon acquired this chassis and it was raced by Wally Dallenbach, Roger McCluskey and Mel Kenyon later in 1971. It was progressively modified over the next three years by Don Kenyon and Eldon Rasmussen, and by 1974 Donald Davidson suggested that it should be called a Coyote - Kuzma - Kenyon - Eagle - Rasmussen. Raced at the Indy 500 by Mel Kenyon in 1972, and by Bob Harkey in 1973 and 1974, and also raced by Kenyon at a few short track races in 1973. It returned to the Speedway in 1976, but Kenyon crashed during practice. Last seen at Ontario later in 1976. History then unknown until 2013, when it was in Bob Boyce's collection (Michigan City, Indiana), still exactly as it had appeared at Ontario.
- Eagle 72  (Lloyd Ruby): Supplied as a monocoque to Lloyd Ruby and his chief crew Mike Devin after Ruby had crashed chassis 7224 at Ontario. Chassis 7228 was built up using the components of 7224 and raced as Ruby's #18 Commander Motor Homes for the rest of the season. Retained in 1974 as a backup car to Ruby's new 1974 Eagle, but actually raced more often than the '74 that season. Sold to Anastassios "Tassi" Vatis, a Greek shipping tycoon and veteran Indy car owner, and run by Vatis's faithful chief mechanic Bill Finley for Johnny Parsons Jr in 1975. In 1976, the team had a "new" car built on an "unused" chassis, presumably 7224 as it still carries the 7224 plate today. However, 7228 remained the main car, Parsons' #93 Ayr-Way/Vatis entry in 1976 and 1977. In 1978, 7228 was modified with straight sidepods and radiators repositioned to the rear of the tub, matching the specification of 7224, after which they are hard to tell apart. John Mahler (Bettendorf, Iowa) bought the Vatis team in November 1978 with the support of longtime backer Richard Deutsch, and it is believed that 7228 was the #92 car that Mahler had bumped after qualifying. Retained as a backup in 1980 and 1981, then sold to Rick DeLorto (Wood Dale, IL) who attempted to qualify for several CART races in 1982. Then to John Griffith (Chicago, IL) 1983, then Steve Burgner (Chicago, IL) 1984, after which it was sold to Mountain View Motorsport Park in Colorado. It then passed to a dealer in Connecticut, from which Eric Camiel (Danbury, CT) bought it in 1991. Then unknown until acquired from Chuck Haines (St Louis, MO) by John Mueller (Fresno, CA) in late 2005. Chuck is believed to have got it from Lilo Zicron (Burbank, CA). Extensively rebuilt by Mueller to standard specification. Sold to Rick and Alison Dresang (Hartford, WI) in May 2016.
- Eagle 74 (Jerry Grant): New to Robert L. 'Bob' Fletcher's Cobre Firestone team and entered as the #55 car for Jerry Grant in 1974. Firestone withdrew from racing In August 1974 and Fletcher, who ran the largest Firestone dealership in the US, had to use Goodyear tyres in 1975. He also lost chief mechanic Jim McGee to Penske. This car became the blue #6 entry for Billy Vukovich in 1975 and then the #3 entry for Bobby Unser in 1976. Probably the car raced by Unser at Phoenix at the start of 1977. To Carl Gehlhausen for 1978 and used by John Mahler as Gehlhausen's #39 entry at the 1978 Indy 500. Also the #39 Gehlhausen entry for Al Loquasto at Indianapolis and Michigan in 1979. Sold to Walter L. Medlin for 1980 and entered as the #32 car for Tony Bettenhausen II at three races; also for Bubby Jones as the #58 at the 1981 Indy 500 but he did not qualify. Remained with Medlin and is part of a collection of unrestored cars photographed on occasions since.
- McLaren M16B  (John Martin): McLaren Cars 1972 for Gordy Johncock (#24) and 'wrecked' at Ontario. Repaired and sold to John Martin 1973 (#89) and 1974 and 1975. Wrecked at Milwaukee June 1975 and tub "thrown in dumpster". Rebuilt using a M16A monocoque bought from Lindsey Hopkins, first appearing in this form at Pocono three weeks later, and raced by Martin to the end of 1975. This M16B/A was acquired by Danny Jones and Roy Dickinson in 1976 and rebuilt for the 1977 Indy 500. They were then joined by Bill Freeman Racing, appearing on the 1977 Indy 500 entry list as #30 Caesars Palace entry. Bob Harkey failed to qualify the car at Indy and it was raced by Johnny Parsons Jr later in the 1977 season. To Fred Ruth for 1978 and qualified for the Indy 500 by Jerry Sneva in 1978 as the #30 Smock Material entry. Ruth was joined and at some point as co-owner by Marv Schmidt. Returned again in 1979, entered by Thunder Racing and with Molly Mate sponsorship. It was next seen in 1981 when John Martin qualified at the Indy 500 but was bumped. Cliff Hucul ran it later that year as the #57. Then unknown until 1991 when it was owned by Chuck Haines (St Louis, MO) and still in Hucul livery.
- Vollstedt 73  (Tom Bigelow): New for 1973 as Vollstedt Enterprises' #17 Norton Spirit entry for Bill Simpson but Simpson crashed during practice for the Indy 500, and the car could not be repaired in time for qualifying. Simpson drove the car again in practice for the Pocono 500, but left the team, saying the car was not fast enough. Bob Harkey took over the drive, and qualified. At the Ontario 500, Tom Sneva was brought into the team, but again crashed the car preventing it from qualifying. The car was converted to the McLaren-style design of the 1972 car for 1974 when it was raced by Bigelow as the #27 Bryant Heating car. Raced by Bigelow at Indy in 1975 but its usage during the rest of that season is still to be determined. Rebuilt extensively for 1976 with its radiators moved to the nose, the same as the 1972 car which had been modified the previous season. Raced by Dick Simon as the #17 Bryant Heating entry in 1976 and in early 1977. It was then retained by the team as a backup car in 1978 and was fitted with an AMC turbo V8 for some races in 1979. Its last known appearance was when driven by Gary Bettenhausen at Pocono in June 1981, when it was described as "an old shovel-nose car". Rolla Vollstedt's son Bruce recalls that the tub sat around for some time, the sides having been taken off with the intention of using it build a different style car. The sides were later put back on, it was sold to to Joe Green, and Rolla rebuilt the car for him in about 2001.
- Eagle 72  (Bill Simpson): New to Patrick Racing for 1973 and identified as their #60 STP entry at the 1973 Indy 500 for Graham McRae. Then became Wally Dallenbach's #40 car after the Indy 500, winning at Milwaukee and Ontario. Sold to Richard Beith (Danville, CA) for 1974 and entered as the #18 American Kids Racer car for Steve Krisiloff and Bill Simpson. Returned in 1975 for George Follmer, now as the #28, but only at Ontario and Indy. Leased from Beith by Warner Hodgdon (San Bernardino, CA) for 1976 and raced by Billy Scott at the Indy 500 before returning to Beith for three more seasons, appearing mainly at the 500-mile races at Ontario and Indianapolis. Retained by Beith until sold to Chuck Haines (St Louis, MO) in October 2005. Haines advertised it in early 2006 still in Beith's American Kids livery. Bought from Haines by Aaron Lewis (Cessnock, NSW, Australia) in September 2008 and restored for him by Walter Goodwin between 2008 and 2011 to McRae's 1973 livery. Ran at the vintage demonstration at the Indy 500 in 2011 and 2012 and then on display at the Riverside International Automotive Museum. Sold at the RM Auctions sale at Monterey in August 2014 to Milton Verret (Austin, TX), but bought back by Lewis in 2018. Sold to Carlos de Quesada (Tampa, FL) at Indy in May 2019.
- McLaren M16C  (Mike Hiss): To Roger Penske for Gary Bettenhausen to drive during the 1973 season as the #5 Sunoco DX car, and used by him at all races that season. Entered for Mike Hiss as the #68 Norton Spirit entry at Indianapolis and Michigan in 1974. Then the #16 CAM2 Motor Oil entry for Bobby Allison at four long-track races in 1975. Then raced by Mario Andretti for Penske as the #6 in 1976 at the Indy 500 and Pocono. Sold to Bill Simpson later in 1976 (still as #6) together with M16C/4. It then became part of Teddy Yip's Theodore Racing team in 1977 as their #39 but was crashed very heavily by Clay Regazzoni in Indy practice. The wrecked car was cubed by Yip.
- Coyote 74 ['74-2'] (AJ Foyt): New for AJ Foyt at the 1974 Indy 500 as Foyt Enterprises' #14 Gilmore Racing entry. Photographs show that it was also raced by Foyt at Milwaukee in June, Pocono, Michigan in July, Milwaukee in August, probably Michigan again in September, Trenton in September and Phoenix in November. It was also used to set a new record speedway lap of 217.854 mph at Talladega on 3 August 1974. Photographs also show that this was one of three cars used by Foyt during the 1975 season: at Ontario in March, as his #10 backup car at the Indy 500, and at both Michigan races in July and September 1975. In 1976, Foyt raced the older 1974 car at early-season short track races and the newer 1975 car at the Indy 500, but used this car for every race from Pocono in June to the end of the season. In 1977, it was raced by Foyt at Ontario and Phoenix in March, TWS in April, Pocono, Mosport, and Trenton in September; and by Billy Vukovich at the Indy 500. In 1978, it was raced by Foyt at Phoenix in March, Trenton in April, Mosport, and Milwaukee in June, by Snider at Pocono, and probably at Michigan, where he hit the wall. It may be the car raced by Foyt in the August Milwaukee and by George Snider in the two races in Britain in October 1978, but this remains uncertain. Foyt then bought Parnelli VPJ6Cs, and the Coyotes were finally retired. This car passed to Foyt's long-time sponsor Jim Gilmore and was on display in his second-floor office in Kalamazoo, Michigan, and was in his living room at his home by 1985. After Gilmore died in a traffic accident in 2001, the Coyote moved to the Gilmore Museum, also in Kalamazoo, which had been founded by his uncle, Donald S. Gilmore in 1966. Its display board calls it a 1974 car, and that it was the Talladega record car.
- Riley 74 (Roger McCluskey): New for the 1974 season and entered by Lindsey Hopkins as the #1 English Leather entry for his reigning USAC champion driver Roger McCluskey. Retained for 1975 when it was the #15 Silver Floss Sauerkraut entry for McCluskey. Retained as a backup for 1976 when Mike Hiss drove it as the #11 Hopkins entry at Indy but did not qualify. Chuck Looper told Pete Klain that Hopkins traded three cars to Rolla Vollstedt, including the Riley, and Vollstedt sold it to Kenny Hamilton (Boise, ID) who fitted a Chevy engine and ran it as the #63 Spirit of Idaho in 1981, failing to qualify at Indy but starting at Riverside later that year. It then went to Terry Nish (Salt Lake City, UT) who used the suspension on a sprint car or supermodified. The chassis and other parts passed through several more owners until sold by Gary Trout (Zionsville, Indiana) to Pete Klain (Beverly Hills, MI). Klain visited Nish and bought the original uprights and started work on a complete rebuild with original fabricator Chuck Looper.
- McLaren M16C  (David "Salt" Walther): New for McLaren Cars at the start of 1973, and raced by Johnny Rutherford at the early short-track events. Possibly used by him at short track events later in the year. Also driven by Peter Revson as the #15 Gulf entry at Pocono and Ontario in 1973, taking pole position at both events. By early November, it had been acquired by George Walther, replacing the older M16 in which Salt Walther had been badly injured at the 1973 Indy 500, and was prepared by Dayton-Walther chief mechanic Tommie Smith from the team's new base in Dayton, Ohio. It was driven by Salt at the Indy 500 in 1974 as the #77 Dayton Walther Spl, but the Walthers then acquired M16C/6, retaining M16C/2 as his #33 spare car at the Indy 500 in 1975 and 1976. It was raced by Bob Harkey as the #33 Dayton-Walther entry at Indy and Pocono in 1975, and by David Hobbs at Indy in 1976. How it was used during the rest of the 1975 and 1976 season is unclear but it was quite possibly used as by Salt Walther a short-track car. Relegated to the team's third car for 1977 when Walther acquired M16C/5 from McLaren. Sold with M16C/6 to Jerry Karl/William R. Compton Sr for 1978, converted to Chevrolet V8 power and entered by Tonco Trailer until 1981 but Karl had two cars and the exact usage of M16C/2 is unclear. Sold to Chuck Haines (St Louis, MO) but had moved to Ron Rickard (San Diego, CA) by 1986 when he drove it at the Palm Springs historics. Sold to Tony Roberts and Duncan Fox (Auckland, New Zealand) in 1997 and used in historics with an aluminium 355 ci Chevrolet V8 from 1998 to 2000. Sold to the Mathews Collection still with its Chevrolet engine. From Mathews to Aaron Lewis (Cessnock, NSW, Australia) in 2009.
- Eagle 74 (Al Unser): Al Unser started the 1974 season in one of two second-hand 1973 Eagles acquired by Vel's Parnelli Jones Racing, before moving to a new 1974 Eagle in time for the Phoenix 150 in mid-March. The team bought three or four 1974 Eagles, so Unser may have used more than one Eagle during the 1974 season, but for now, it is assumed all his results were in the same car. Vel's Parnelli retained the same Eagles for 1975, but the "super team" were in decline, and only appeared at the three 500-mile races. Again, it is assumed here that Unser used the same car as in 1974. The team was disbanded in July, when when it returned, it focused on the new Parnelli VPJ6. The subsequent history of the Unser Eagle is unknown.
- Eagle 72  (Jerry Karl): Acquired by the Lindsey Hopkins team at some point late in 1972. It is not yet clear where Lee Kunzman first raced this car for Hopkins, as his #10 car in 1972 was a 1970 Eagle, and only photographs will show exactly where each car was used. The 1972 Eagle was Hopkins' #16 Ayr-Way Lloyds entry for Kunzman, and then became the #16 US Air Force entry for Bentley Warren later that season. It became the #42 Hopkins Buick entry for Jerry Karl to race in 1974. It was wrecked by Karl at the Indy 500, and team crew Duane Glasgow rebuilt it using the 7211 tub to run at Pocono and Michigan with Bentley Warren driving again. Warren had a tyre blow at Michigan in July, hit the wall and wrecked the 7211 tub. Duane then repaired the 7215 tub and had the car ready for Michigan in September with Mel Kenyon driving, but he hit the second turn wall heavily. Neither tub was repaired for racing again and both were later sold by Glasgow to Fred Fuhr (Hastings, MI) who sold them in 1981 to Bill Wiswedel (Holland, MI). Bill sold 7215 to restorer Walt Goodwin in the early 1990s who sold it to his customer Jim Jaeger for whom he then restored it to 1973 Indy 500 form. Run at the Goodwood Festival of Speed in 1999. Jaeger retained the car in 2010.
- Kingfish 73 ['1'] (Tom Sneva): Built by Grant King for Steve Krisiloff to drive in 1973 as the #24 Grant King Racing entry, acquiring many different sponsors during the season. This car started the season red but was repainted blue-and-yellow after qualifying for the Indy 500. Retained the number #24 for 1974 but now driven by Tom Sneva, scoring a fifth place finish at Michigan in September 1974. Retained by the team for 1975 and raced by Bentley Warren at the Indy 500 but crashed in the rain and was very badly damaged. Parts of the car were used to build up a new chassis and what was left of the car remained with its 1973 sister car until both were sold as a project on race-cars.com in 2009 to Rick and Jacques Dresang (Hartford, WI).
- Eagle 72 (Steve Krisiloff): Patrick Racing had started 1973 with three 1972-style Eagles, and then bought two 1973 Eagles later in the season. By the time the team got to the 1974 Indy 500, they had also acquired two 1974 Eagles but the three 1972 Eagles were all gone, one destroyed and two sold. Patrick Racing started the month with Gordon Johncock (#20) and Wally Dallenbach (#40) in the new 1974 Eagles, but Johncock damaged his, so one of the 1973 cars was bought to Indy for him to race. The other 1973 car was entered for Steve Krislioff (#60) but his qualifying picture shows him in a 1972 Eagle, not the '73 car. So which 1972 car could this be? The most likely answer is that this was 7227, the car listed in AAR records as having gone to Patrick Racing. If so, it is likely that this car was used at some point during 1973, but no photographs have yet been found of it being used. Krislioff also raced this car at Milwaukee in June, after which he was allocated the team's newer 1973 Eagle. This is believed to be the car that STP donated to the Indianapolis Motor Speedway Museum in April 1977, when STP decide to donate its 15 show cars to different museums. This car was donated as being Gordie Johncock's 1973 Indy 500 winner, and placed in the IMS Museum, but was later admitted to be a replica. It remained in the museum until June 2010 when it was replaced by the real car.
- Eagle 74 (Jimmy Caruthers): New to Robert L. 'Bob' Fletcher's Cobre Firestone team and entered as the #21 car for Jimmy Caruthers in 1974. Firestone withdrew from racing In August 1974 and Fletcher, who ran the largest Firestone dealership in the US, had to use Goodyear tyres in 1975. He also lost chief mechanic Jim McGee to Penske. This car became the white #11 entry for Duane Carter in 1975. Unknown in 1976 but presumably a backup car for Bobby Unser's regular #3 car. Sold to Carl Gehlhausen and entered for Spike Gehlhausen as the #19 PV Corp car at four races towards the end of the 1977 season and then through the 1978 season, until it was crashed heavily at Michigan in September. Gehlhausen then bought Pat Santello's '74 Eagle to replace it. The Michigan wreck is believed to have been repaired for 1979, and may be the car sold to Todd Gibson for 1980.
- Eagle 70  (Larry Cannon): New to the Jud Phillips half of the Leader Card team for Bobby Unser to race at the 1970 Indy 500. However, Unser preferred his usual 1967 car and the 1970 car was only used in practice. According to a later Hungness yearbook, the car was entered as a spare in 1971 and in 1972 and raced at least once during those three seasons, by Rick Muther in the 1972 California 500. Acquired by Gus and Richard Hoffman (Milford, OH) of Hoffman Racing and entered for Larry Cannon in 1973 as the #59 PEP Gas Treatment Spl. Returned in 1974 and qualified for the 500, now with American Financial Corp backing. Used again in 1975 before the team acquired a newer 1973 Eagle for the 1976 season. Subsequent history unknown but the ex-Unser, ex-Cannon car advertised by Robert Pass (Maryland Heights, MO) in 1992, having been restored by Jim Robinson. Later advertised by Chuck Haines (St Louis, MO) as being chassis 803. The car had been restored to Cannon's 1974 livery.
- McLaren M16B  (Jim Hurtubise): To Roger Penske for Mark Donohue to drive in 1972 as the #66 Sunoco DX McLaren. Won the 1972 Indy 500 and also second at the Ontario 500-mile race when driven by Mike Hiss. Sold to George Walther late 1972 for Salt Walther to drive in 1973, but this was not the car Walther drove in the 1973 Indy 500. By November 1973, this ex-Donohue car had been sold by the Walther operation to Jim Hurtubise, and would be the car he entered at Ontario in September 1973. It was then his #56 Miller High Life entry at the Indy and Pocono 500-mile races in 1974. Retained and appeared at Indy as an unused backup until at least 1978. Subsequent history unknown but at some point to the IMS Museum and restored as Donohue's 1972 winner.
- Finley 73 (Johnny Parsons Jr): This car is often described as a Fleagle (e.g. the 1974 Hungness and the 1973 Daily Reports) but the descriptions are sufficiently consistent to be able to pinpoint this as a 1973 car built by Vatis Chief Mechanic Bill Finley (Hungness 1974 p124) as the car used by Parsons at both the 1973 and 1974 Indy 500s. All other references to Finley-Eagles, Finleys and Fleagles wearing #94 in 1973, 1974 and 1975 are presumed to be this same car. In 1975, the Vatis team acquired at old 1972 Eagle which was run as the #93 car with the 1973 Finley retaining the number #94. In 1976, a new Eagle was built on a "spare tub" and took the number #93 after which the 1973 Finley appears to have been retired.
- Coyote 72 ['72-1'] (Rick Muther): Built new for AJ Foyt for the 1972 Indy 500, where he qualified in 17th position on day 2, with the fifth fastest time, but retired early. Foyt was injured at DuQuoin the day after the 500 and did not return until Ontario in September, by which time he was reported to have built a new car. However, later history would suggest this was the same car, but with some updates. He led at Ontario, but retired at all three of the remaining races of the season. The car was sold to Lee Brayton for 1973 as the #61 Diamond Reo entry, with John Gleason as his chief mechanic. Brayton raced the car at TWS and Trenton early in the season, but he was unable to qualify for the Indy 500. After damaging the Coyote at Ontario later in the season, Brayton bought the ex-Gordy Johncock 1972 Eagle from Patrick Racing. The Coyote was rebuilt and retained by Brayton as a backup for 1974, still as the #61, and was qualified for the Indy 500 by Rick Muther. After Brayton damaged his Eagle in practice at the Indy 500, he raced the Coyote one more time at Pocono. The car is reported to have gone to Patrick Racing as a show car and presumably was the Sinmast Special Coyote loaned to an Indianapolis bank in May 1975. However, Brayton had acquired sponsorship from Sinmast, who later sponsored Patrick, so maybe it was actually owned by Sinmast. The car's history is then unknown until it was found in "a Chevrolet dealership in Carmel, a northern Indianapolis suburb, in 1984" by Thomas W. Acker (Largo, FL). Acker displayed the car at a car show in Florida in 1990 still in #20 blue-and-white Patrick livery. It was acquired from Acker by Vonnie Sue Martin for her husband Ron Martin (Bluff City, TN) in 2005 and restored to its 1974 configuration by Walter Goodwin. Martin displayed it at the IMS in 2008 and 2011, after which he sold it to Charles Ungurean (Columbus, OH). Ungurean sold it to Bruce Revennaugh (Marble Falls, TX) in 2014. Displayed by Revennaugh at the Indianapolis Historic Indycar Exhibition in May 2017.
- Atlanta 72 (George Snider): New to AJ Foyt, and entered for the 1972 Indy 500 as the J.H. Greer #82 car, but did not arrive. The car was fitted with a Foyt-Ford V8 engine, and was entered at Indy a year later for Jim McElreath to drive, but he did not complete a qualifying attempt. It was brought out again in 1974, still as the #82 entry, and was driven by George Snider at Ontario Motor Speedway in March, at Phoenix two weeks later, and also at the Indy 500, where Snider qualified 13th but retired early. Photographs show that it was also raced by Sammy Sessions at Michigan, wearing #83. For 1975, the Atlanta was sold to Carroll Cheek (Bowling Green, Ohio), fitted with a Chevrolet engine, and entered in a couple of USAC races at Phoenix for Formula B racer "Butch" Harris (Houston, TX) to drive, Harris having driven Cheek's Supermodified racer. The car did not start a race, and it's unclear whether it even got to practice. In early 1977, it was sold to George R. Boyd (St Joseph, IL) and the Chevy engine was replaced by a Foyt-Ford acquired from Tom Frantz. Frantz was given the chance to qualify it at the 1977 Indy 500, but he spun during practice and Jerry Karl, Bob Harkey, and Mel Kenyon were all given a try in the car. It went well during the month but Kenyon was unable to rediscover that speed during his qualifying run. The car was retained by Boyd in his garage for over 40 years until his death in January 2018. Six months later it was sold to restorer John Mueller.
- Eagle 74  (Mike Mosley): Mike Mosley's #98 1974 Indy 500 drive for the Lodestar/Leader/Agajanian/Watson combine and identified in a letter from AAR to USAC in Feb 1974 as 7417. Said to be the #98 for Steve Krisiloff in 1975 but the #98 picture in the 1975 yearbook is clearly a 1972 car. Could this be the car Krisiloff wrecked at Phoenix at the end of 1974? It might also be the one he "damaged extensively" in practice at the 1975 Indy (6 May - see trackside report); although the 14 May trackside report says this car was rebuilt, it is an older '72 car that Krisiloff races. Later in 1975, Agajanian left Lodestar/Leader/Watson taking his #97/#98 numbers with him and joined Grant King. Krisiloff's Lodestar/Leader/Watson Eagle then took #10 for the rest of 1975, then moved to the #23/#24 numbers in 1976. Krisiloff may have raced the '74 car later in 1975 but it is not yet known how long the car took to rebuild. At Indy in 1976, Tom Bigelow is bumped in the Leader Card #24 entry which looks like a '74 Eagle but is modified around the front suspension. Maybe 7417 with suitable repairs? Again, the usage of this car in 1976 cannot yet be determined. In 1977, Joe Saldana was bumped in the #64 Leader Card entry, a standard-looking Eagle 74. A picture shows that Saldana's #23 car at the next race was also a '74 Eagle. Finally, at the 1978 Indy 500, Tom Bagley is pictured in Hungness driving a '74 Eagle in practice. Subsequent history unknown.
- Eagle 74  (Wally Dallenbach): New to Patrick Racing and identified by an Indianapolis 'Laycock card' as Wally Dallenbach's #40 STP entry in 1974. Given the early construction date, marked as January on the chassis plate, this car is assumed to be Dallenbach's ride from the start of 1974. Presumably his early-1975 car before the new Wildcats were ready. At Indy 1975 as the #60 spare. Sold to Leader Card Racers for 1976 and George Snider's #23 Hubler Chevrolet ride in that year's 500. Also for Mike Hiss at Ontario. Retained for 1977 and the #64 at the Indy 500 but thought to be the #23 at other races. Retained again for 1978 but wrecked in Tom Bigelow's accident at Mosport Park in June. Bought from AJ Watson by someone called Al in Grand Rapid, Michigan and sold by him to Bill Wiswedel (Holland, Michigan) around 2000-2004. In approximately 2017, Bill sold the car to James Long (Nevada City, CA) and he sold it to Bobby Rahal (Chicago, IL) in 2020.
- Eagle 74  (Mario Andretti): The 1975 Hungness year book says that Mario's Andretti's #21 car was the same #5 car he had driven in 1974. The car was wrecked at Indy in 1975 and the 1976 Hungness appears to say that the repaired tub was used to rebuild the Routh team's ex-Patrick Eagle 74. Presumed to have been Andretti's car from the start of 1974 until his wreck at Indy in 1975. The "original" #5 1974 Eagle was advertised for sale in the early 1990s, mentioning chassis number 7406, but it is not clear whether this is the ex-Routh car or something different.
- McLaren M16C  (Gary Bettenhausen): New to Roger Penske for Bobby Allison to drive at the 1973 Indy 500 as the #12 Sunoco DX car. Sold to Roy Woods and appeared at Ontario in August/September 1973 as the #74 Carling entry for John Mahler, who crashed it in the race. It evidently returned to Penske and was rebuilt as the #8 entry for Gary Bettenhausen in 1974. Used by Mike Hiss after Bettenhausen was injured in a dirt race in July 1974. Taken over by Tom Sneva in 1975 as the #68 Norton Spirit entry but wrecked in Sneva's huge accident at Indy in 1975. Rebuilt later in the season and rejoined the Penske team to be a backup car for Sneva in 1976. Its last known appearance was at Michigan in July 1976. History then unknown until 2009 when it was part of the Harrah Collection at the National Automobile Museum (Reno, NV). Presumably it had been bought by Bill Harrah, founder of Harrah's Casinos. After Harah's death in November 1978 his 'Harrah’s Automobile Collection' was acquired by Holiday Inns and started to be broken up and auctioned in the mid-1980s. In response to ensuing outcry, Holiday Inns agreed to donate 175 cars and Harrah's research library to a new Harrah Automobile Foundation and this became the basis of the National Automobile Museum which opened in Reno, Nevada, in 1989. The car is in Sneva's 1977 red, white and blue Norton/Gould/CAM2 livery, suggesting it was used as a show car in 1977.
- Eagle 72  (Dick Simon): To Dick Simon, fitted with a Foyt-Ford V8 turbo engine and first raced as his #44 Travelodge entry at Phoenix in November 1972, where he was second fastest in Friday practice. Raced by Simon through 1973 and 1974 as the #44, retaining its Travelodge sponsorship until mid-1974. Returned in 1975 with Bruce Cogle Ford backing and in 1976 with Lan Hairpieces and later Robyn CB sponsorship when it was driven by Roger Rager. Not at Indy in 1977 but later in the year it was acquired by Nick Krantz and entered for Phil Threshie, still as the #44 but now with Mr. Golden Sunflower sponsorship. Crashed by Threshie in practice for the 1977 California 500 at Ontario and not seen again.
- Eagle 72  (Jim McElreath): Built in the fall of 1972 as one of the two replacement Thermo King/Gerhardt cars after Malloy's crash at Indy in 1972. Used by Mike Hiss in the 1973 500 as the #6 car; then the #46 car used by Jim McElreath in practice in 1974; then the #46 car used by Rick Muther and Jan Opperman in practice in 1975; then the #45 car qualified by Gary Bettenhausen in 1976. After Eddie Miller wrecked the sister Gerhardt Eagle (7209) at Indy in 1976, 7216 was driven by Bettenhausen and Steve Krisiloff for the rest of 1976. Sold by Fred Gerhardt to Gary Howard when Gerhardt stopped racing but not raced by Howard, and sold to Bob Featherly (East Syracuse, NY) about 1980/81.
- Eagle 72  (Lee Brayton): New to Patrick Racing and raced by Gordy Johncock in 1973 as the #25 Patrick Racing entry early in 1973 and then became the #20 STP Double Oil Filter Special at the Indy 500 when Patrick Racing picked up STP sponsorship. Johncock won the Indy 500 in this car but it was wrecked at Pocono in July when a wheel came off and then damaged again at Milwaukee in August in an incident with Johnny Rutherford while Johncock was leading the race. The Eagle was repaired, sold to Lee Brayton and John Eisenhour, and raced by Brayton at Michigan in September 1973 as the #61 Eisenhour-Brayton car, replacing the team's 1972 Coyote. Retained for 1974 when it was Brayton's #28 car, also driven by Mike Hiss at Ontario. Wrecked by Brayton at Indianapolis during practice on 7 May when Tom Bigelow spun in front of him, and extensively damaged, the Daily Reports noting that the Eagle was "apparently a complete loss". Brayton had to return to the old Coyote for Pocono and it is not clear whether he raced the Coyote again at Michigan later in the year or whether the Eagle had been repaired. Retained by Lee Brayton and undergoing restoration at Walter Goodwin's workshop in May 2010. In June 2010, it appears that this car was placed in the Indianapolis Motor Speedway Museum, replacing the mueum's replica of Johncock's 1973 Indy 500 winner. Sold to Bruce McCaw around 2012.
- Eagle 72  (Mel Kenyon): Driven by Mel Kenyon for the Lindsey Hopkins team over three seasons. It was first raced at Ontario 3 Sep 1972 and was the #23 in 1972 and then the #19 in 1973 and 1974 after being converted to Foyt-Ford power by Eldon Rasmussen. Its tub was used to rebuild 7215 in 1974 but was damaged at Michigan in July when Bentley Warren hit the wall. When the two Eagles were retired, they were sold by Hopkins crew Duane Glasgow to Fred Fuhr (Hastings, MI), who sold them to Bill Wiswedel (Holland, MI) in 1981. Bill sold 7211 to Chuck Haines (St Louis, MO) in 1982 or 1983, who sold it on to Dale Bargman (Denver, CO) in February 1984. Bargmann (later of Gilbert, AZ) fully restored the car but its later history is unknown.
- Cicada 72 (Jigger Sirois): Built for 1972 and loaned to Leader Cards, Inc.for the 1972 Indy 500. It was listed as Mike Mosley's #87 backup car, but he focused on his #98 Eagle, and the Cicada became the #97 entry for Bruce Walkup to complete his refresher test on 18 May. The following day, Jigger Sirois also used it for his refresher test and then attempted a qualifying run in the Cicada on 21 May but the engine blew up on his first warm-up lap. The car was not seen again for over a year until raced as the #93 Cicada Racing entry for Jerry Karl at Milwaukee in 1973, finishing 11th. It reappeared in 1974 when it Bob Harkey raced it as the #93 Cicada Racing entry in the first few races of the year,. It is possible that the car was present at more races in 1973 and 1974 but was unable to qualify and unmentioned in reports. It became the #25 Adams Automotive entry for Jigger Sirois at the 1974 Indy 500 but did not qualify and was then driven by Dan Murphy for Adams Automotive later that season. Murphy had a massive accident in the Cicada during practice at Phoenix at the end of the season and the car was destroyed. A second generation Cicada was built for 1975.
- Kingfish 73 ['2'] (Bentley Warren): Built by Grant King for the 1973 season and appeared at the Indy 500 that year as the #75 entry for Greg Weld. Weld did not qualify but this car remained red and is therefore the car raced by Steve Krisiloff as the #24 entry on short tracks in 1973. In 1974, this second Kingfish was numbered #26 but only raced twice with that identity, at the Indy 500 with Bentley Warren and at Pocono in the hands of Bob Harkey. It also raced at some other tracks as the #24 but can be distinguished by its unmodified roll hoop. In 1975, the car was raced again at the Indy 500 by Sheldon Kinser, now as the #19 entry. King joined forces with JC Agajanian for 1976 and both 1973 Kingfish were used in the early races, this one as the #98 car for John Martin and later as the #96 for Bob Harkey. The cars reappeared in 1979, fitted with Chevrolet V8 engines and this car took sixth place at Milwaukee driven by Gary Bettenhausen. Its long race career was finally terminated by an accident in practice at Watkins Glen when driven by Tony Bettenhausen II. The car was advertised by racecars.com in 2009. In 2010, it was reported to be in southern California.
- Eagle 72  (Sammy Sessions): Sold new to Henry "Smokey" Yunick to be fitted with Yunick's own 207 ci turbocharged Chevrolet V8 and transmission but not ready in time for the 1972 Indy 500. First raced by Jerry Karl as the #83 at Ontario in September. Raced at the three 500-mile events in 1973 by Karl, and also by Sammy Sessions at Pocono in 1974 but failed to qualify at Indy. Returned to Indy again in 1975 for Karl where it finished 13th. Later donated to the Indianapolis Motor Speedway Museum but the car is not regularly exhibited and in 2007 was said to be in the basement of the museum. In April 2008, it was on display at the Honda Collection Hall in Japan in connection with the Indy Japan 300 at Motegi.
- Eagle 72  (Denny Zimmerman): The prototype 1972 Eagle was tested over the winter and then used as AAR's #6 Olsonite entry for Bobby Unser on "the mile tracks" during 1972, winning at Phoenix, Trenton, Milwaukee and Phoenix again in November. Sold to Stan Malless, Bob Voigt and Dick Sommers of MVS and converted to turbo Ford engines. Raced for MVS by Sammy Sessions as the #9 in 1973 then reappeared at the 1974 Indy 500 for Denny Zimmerman and at the 1975 Indy 500 for various drivers but did not qualify for either race. Then almost certainly the #72 Custom Motor Home car raced by Tom Frantz (Littleton, CO) in 1976 which went to Ed Crombie (Williams Lake, British Columbia, Canada) for 1977, when it was driven by Larry Cannon and Jerry Sneva. Crombie still had the car in 1983 when he ran it at the Knox hillclimb (Kelowna, British Columbia). History then unknown until advertised by Bob Jordan's Investment Motorsport Inc (Glenview, IL) in June 1990, when it still had its Ford engine and was said to be unraced since 1976. At some point the car was restored by former AAR fabricator Mike Lewis to its 1972 livery and with an Offy engine. It appeared in this specification at the Amelia Island concours in 2002, and was raced by Bob Jordan (Winnetka, IL) at Road America in July 2006. It was offered at the Gooding & Co Pebble Beach auction in August 2008 but did not sell. In 2010, the car was featured on a 'The Motorcar Society' video.
- Kingfish 72 ['2'] (Bill Puterbaugh): The second new 1972 Grant King car appeared for the first time at the Indy 500 as the #15 car for Steve Krisiloff. As the other 1972 car was destroyed in Merle Bettenhausen's accident at the 1972 Michigan 200, it would be reasonable to assume this is the 1972 Kingfish acquired by Carl Gehlhausen's Mid-West Manufacturing Dura-pot team. A Racing Pictorial photograph shows that it first appeared as the team's #58 entry at Phoenix in November 1972, but driver Larry Dickson did not start. It was raced as the #58 by Dickson at the start of 1973, and was driven by Johnny Parsons Jr, Arnie Knepper, Tom Bigelow and Tom Sneva later that season. The Gehlhausen team only made a couple of appearances with the Kingfish in 1974, but made a more concerted effort in 1975, with the Kingfish now as the #38 entry, raced initially by Jerry Karl, and then by Al Loquasto, Jerry Sneva and Mike Hiss (who crashed it) in practice for the Indy 500. Spike Gehlhausen, Carl's son, was then given his first chance in the car after the 500 and kept the drive to the end of the season. The Gehlhausens then acquired a McLaren M16 as the #19 Spirit of Indiana entry, and the Kingfish acted as backup until an Eagle was acquired in mid-1977. Subsequent history unknown but at some point the car was repainted with Sta-On Glaze livery, Gehlhausen's 1979 sponsor. By 2008, it was part of a collection of unrestored Indy cars owned by Walter Medlin.
- Eagle 68  (Larry Rice): Roger Penske bought a road-racing version of the 1968 Indy Eagle and Mark Donohue raced it at Mosport and Riverside that season with a Chevrolet V8. It went to Weinberger Homes for 1969 and was driven at Indy by Ronnie Bucknum. It was then Arnie Knepper's car in 1971/72 and then became the famed LaWarre Precision Eagle entered by Robert W. LaWarre Sr (Titusville, FL) for Larry Rice and John Hubbard in 1974 and 1975. It was then retired but remained in LaWarre's ownership until his death in April 1997. It was bought by Joe Pirrotta (Palm City, FL) in 1999. The Eagle was fully restored to Penske livery and appeared at the Amelia Island Concours d'Elegance in 2005.
- Mongoose 71 (John Cannon): New for Lloyd Ruby in 1971 as the Gene White team's #12 car but "abandoned by Ruby after that year's Indy 500", presumably as it was the only year for some time that he had not led the race. Sold to Pat O'Reilly and entered as the #51 Minnesota Serendipity car in 1973 for Dee Jones, John Hubbard and Jigger Sirois. Returned in 1974 as the #53 for John Cannon but failed to qualify for the Indy 500. Raced later in 1974 by Jan Opperman and by Mel Cornett and appeared in 1975 for John Hubbard and Cornett again. Wrecked at Milwaukee in June 1975 and, according to Milwaukee Mile Historian Steve Zautke, was "wiped out".
- RasCar-Atlanta 74 (Eldon Rasmussen): New for Lloyd Ruby at the Jimmy Bryan 150 at Phoenix in March 1972, where it was Gene White Racing's #5 Wynns entry, and then used by him at the Indy 500, where he finished sixth. Ruby then tried the team's Lola T270 at Milwaukee, and tried both cars in practice at Pocono before it was rained off. He then crashed the Atlanta before the race at Michigan in July, and used the Lola for the rest of the season. Almost certainly the Atlanta-Ford sold to Loyd Meek's Quality Racing Team for 1973, where it was due to be enginered and raced by Eldon Rasmussen, but Rasmussen did not appear in the car until Texas in October, where it went very well. Rebuilt by Rasmussen as a "Ras-Car", and thereafter described as a 1974 car. Raced by Rasmussen in the 1974, 1975, 1976, 1977 and 1978 seasons, although he generally only appeared for the longer races at Indianapolis, Ontario, Pocono and Michigan. This is believed to be the car that was demolished in Rasmussen's huge accident at Pocono in 1979.
- RasCar-Atlanta 74 (Larry McCoy): Completed by Gene White Racing after Atlanta Cars closed, and first seen as the team's #21 Bill Daniels GOP for Cale Yarborough at the 1972 Indy 500. Yarborough was then "asked to step down", and the car was converted from Ford to Offy power for team leader Lloyd Ruby to try in practice at Pocono. It was raced by Jimmy Caruthers as the #52 Wynn's Special at Ontario in September. Almost certainly the Atlanta-Offy sold to Larry McCoy Sr's Eastern Racing for his son Larry McCoy to drive in 1973, backed by James Bidwell's Shurfine Foods. Converted by Eldon Rasmussen to Ras-Car specification for 1974, and raced by McCoy and others up to 1977. To Frank Fiore for 1978, and his #87 Machinists Union entry for Jerry Karl, Phil Threshie and Al Loquasto that season. Then to Buddie Boys, a Calgary trucking magnate, and entered for Bob Harkey at the 1980 Indy 500, but he could not get enough speed out of it. The last that was heard of the car was just before the Milwaukee race, when the engine was said to have blown up during testing.
- Eagle 72  (John Mahler): New to Roy Woods Racing and entered for David Hobbs at the 1973 Indy 500 as the #73 Carling Black Label entry. For Hobbs at Pocono then John Mahler at Ontario that season. Woods then lost the Carling sponsorship but returned to Indy in 1974 with the Eagle as the #69 entry for Mahler who failed to qualify. Next seen in 1976 when owned by by Gus and Richard Hoffman (Milford, OH) of Hoffman Auto Racing and entered as the #69 American Financial Spl for Larry Cannon at various races that season. Returned to Indy in 1977, again as Hoffman's #69 entry, but crashed by Jerry Grant in practice and "extensive damaged". Reworked by the Hoffman team as their 1979 #79 'Spyder' Indy car and raced by Dick Ferguson, Joe Saldana and others. Crashed heavily by Bob Frey in practice at Pocono 1980 and effectively destroyed.
- McLaren M16C [M16-1?] (John Mahler): To Roger Penske at the 1971 Indy 500 for Mark Donohue (#66 Sunoco). Donohue retired from the Indy 500 but his car was later "destroyed" when Mike Mosley crashed his Eagle into it. It was said that nothing was salvageable and a new car (M16-4) was built in time for Pocono. However, detailed study of photographs establishes that M16-1 was rebuilt and was raced by Gary Bettenhausen for Penske at short-track races in the first half of 1972. Sold to Roy Woods Racing for John Mahler (#74) at Ontario 1972 but wrecked in the race. Not seen again until entered by Roy Woods for David Hobbs (#73) at Ontario September 1973 then for Mahler (#74) at the 1974 Indy 500 but DNQ. It had been updated to M16C form during this time. Sold to Al Loquasto, replacing the M16B he had previously raced, and used from 1975 to 1978 as Loquasto's #86 Frostie Root Beer entry. Loquasto may have used his M16B at some tracks, but no photographic evidence has yet been found for that. Sold by Loquasto to Robert W. LaWarre Sr. (Titusville, FL) for Tony Bettenhausen II (#86 Tilton) late 1979. History then unknown until the M16 was bought from someone in Florida by Joe Baird (Shelbyville, IN) and a partner in the 1990s, when the car still had Loquasto and LaWarre bodywork. Sold via Jim Mann and Steve Truchan to former Formula Atlantic driver Glen A. Smith (Rockwall, TX) and retained by Smith until his death in 2008, after which his wife sold it to Bob Boyce (Michigan City, Indiana).
- McLaren M16B  (Al Loquasto): Roger Penske 1972 for Gary Bettenhausen (#7) at the Indy 500, Michigan and Pocono in July. Raced by Gordon Johncock at Milwaukee in August, again as the #7, and then became Mark Donohue's #66 entry at Trenton and Phoenix. Believed to be Bettenhausen's #5 car at Texas World Speedway in early 1973, after which it was sold to Al Loquasto and was the car he crashed during practice at the Indy 500. Raced by Loquasto for the rest of 1973 and retained in 1974. Unknown thereafter but presumably retained as a backup to his ex-Roy Woods McLaren M16C until 1979 and maybe used on short tracks. Sold with the M16C to Robert W. LaWarre Sr (Titusville, FL) in 1979, and retained by LaWarre until his death in 1997, after which it was sold as a bare tub to Penske in the late 1990s. Penske also obtained from the Goodyear Museum a show car that Penske had built using a replica tub and the bodywork from the 1972 cars. The bodywork and running gear was reunited with the M16B monocoque and restored as a replica of Mark Donohue's Indy 500 winner. The car has been on display in the Penske Racing Museum (Scottsdale, AZ) since 2012 or earlier.
- Finley 73 (Bentley Warren): This car is often described as a Fleagle (e.g. the 1974 Hungness and the 1973 Daily Reports) but the descriptions are sufficiently consistent to be able to pinpoint this as a 1973 car built by Vatis Chief Mechanic Bill Finley (Hungness 1974 p124) as the car used by Parsons at both the 1973 and 1974 Indy 500s. All other references to Finley-Eagles, Finleys and Fleagles wearing #94 in 1973, 1974 and 1975 are presumed to be this same car. In 1975, the Vatis team acquired at old 1972 Eagle which was run as the #93 car with the 1973 Finley retaining the number #94. In 1976, a new Eagle was built on a "spare tub" and took the number #93 after which the 1973 Finley appears to have been retired.
- Eagle 72  (Lee Brayton): New to Doug Champlin & Fred Carillo of Champ Carr, Inc.and entered at Indy in 1972 as the #34 Norris Industries entry for Sam Posey. This car was not seen in the Champ Carr team during 1973, but was presumably the #31 entry at the Indy 500, that Carillo substituted illegally for the team's #34 car chassis 7226) which had already been bumped. To Marvin Webster (Mill Valley, CA) for 1974 and his #76 Webster Racing entry for the next three seasons, although Webster also had a 1966 Eagle used on short tracks. At Ontario in September 1976, John Mahler was entered in a "Webster-Offy" but a photograph shows that it was the team's usual Eagle. It was wrecked during the race and no Marvin Webster entry appears again. History then unknown, but later in the collection of Bruce McCaw (Seattle, WA). From McCaw it went to Ray Cooke (Langley, WA), and in late 1995 was advertised in Autoweek by Craig Coyer, a Seattle used car dealer who had taken it as trade on a Porsche. It was bought from him in 1996 by Greg Scott (Del Mar, CA), who found it to be virtually complete. Scott ran the car in the Victory Lane/VARA Indy Car Historics at Fontana from about 1997 to 2001 or 2002. It also appeared at Del Mar's 'Vehicles of Character' car show in September 2004. Since then, it has been in storage.
- Eagle 74  (Billy Vukovich): New to Jerry O'Connell's team for 1974 and raced by Billy Vukovich as the #4 Sugaripe Prune Special. Presumably the car used through 1974 by Vukovich and then through 1975 by Mike Mosley but the team had older 1972 Eagles available and those older cars may have been used at some races. Used again by Mosley in 1977 but O'Connell also acquired a new Lightning for that season. Sold after Pocono in July 1978 to Jim McElreath, who had damaged his ex-Patrick 1973 Eagle at that race. Identified by Simmo Iskül from photographs as McElreath's #23 in 1979, and presumed to be the McElreath Racing #23 right up to 1981, although the ex-Patrick car was also repaired and used again. Subsequent history unknown, but at some point in the next 30 years the car was acquired by Chuck Haines and restored to it original Sugaripe Prune livery. For reasons currently unknown, Haines advertises the car as chassis 74-08.
- Parnelli VPJ-3  (Mario Andretti): The new VPJ3 debuted at Trenton for Andretti (Davidson p13). All earlier Parnelli appearances must have been VPJ2s.
- Coyote 74 ['74-1'] (AJ Foyt): New for the start of the 1974 season, and raced by AJ Foyt as Foyt Enterprises' #14 Gilmore Racing entry at Ontario, Phoenix and Trenton. Foyt crashed in practice at Trenton and returned to base. He then raced a new, second,1974 Coyote at the Indy 500, and the only times this older car was seen was as his #10 backup car used in practice for the Indy 500, and then as the #10 entry driven by George Snider at Michigan in September. This older car was almost certainly the team's backup car at the start of the 1975 season, when it was the #10 entry prepared for Joe Leonard at Ontario in March 1975, and raced by Rick Muther after Leonard failed a medical. Photographs show that the same car was used by Foyt at short track races that season: Phoenix in March, Trenton in April, Milwaukee in June and August, Trenton in September, and Phoenix in November. This car reappeared at the start of 1976, now updated with the same style of bodywork used on the other 1974 car the previous year, and was raced by Foyt at Phoenix in March, Trenton in May, Milwaukee in June, and Trenton In August, where Foyt clipped the wall and retired with broken suspension. The car was not seen at all during 1977, and probably not in 1978, although this still remains uncertain. This car was not in the Foyt auction in 1992, and its current whereabouts are not known. One possibility is that it was extensively rebuilt as the 1978 car.
- Eagle 74  (Lloyd Ruby): New to Mike Devin's Unlimited Racing Team, who was expecting to be Lloyd Ruby's chief mechanic on the car as part of the Parnelli team, but was sold on to Mike Slater's Commander Motor Homes, still with Ruby as driver and Devin as chief mechanic. Ruby also owned a 1973 car, chassis 7228, which was his short track car in 1974. Entered by Devin for Sammy Sessions at the 1975 Indy 500, then Bob Fendler (Phoenix, AZ) bought the '74 Eagle, setting up a new team in Phoenix, with Devin relocating to be chief mechanic, and Ruby again as driver in the November 1975 Phoenix 150. Fendler's empire then collapsed, and the Eagle returned to Devin. After Ruby's last Indy 500 appearance in the car the following May, Devin joined Lindsey Hopkins' team in July 1976, and leased the Eagle to Bobby Hillin's Longhorn Racing, later selling the car to Hillin in 1977. It was Hillin's #18 Spirit of Truth entry in 1976 for Jan Opperman and George Snider, then Hillin's #72 entry for Bubby Jones at Indy 1977, and then the #18 again for Snider later in the year. It was entered by Hillin for the 1978 Indy 500, but only as a backup. This was then the 1974 Eagle entered as the #81 Dairy Queen car for Billy Vukovich and Roger Rager later in 1978, in what became the John O'Hanlon/Wayne Woodward Shade Tree Racing, although whether O'Hanlon and Woodward had joined forces as early as 1978 is unclear. It was run for Dick Ferguson and Jerry Sneva in 1979 and then appeared at two more races for Michel Jourdain in 1980. It was next seen when Steve Culp (Shreveport, LA) bought it from Mike Gue of Essex Racing some time between 1982 and 1984. Gue was an English dealer who moved his operation to Connecticut in 1981, then to Atlanta, Georgia, in 1983. Culp moved the car to Shreveport about 1985, where it remained, still in Jourdain's livery. It was bought by Danny Aiello (Marshall, TX) in 2020.
- Eagle 74  (Gordon Johncock): New to Patrick Racing and identified by Gene Lee Gibson as Gordon Johncock's #20 STP entry in 1974. Entered in the early-1974 races as the #7 Patrick Racing car until a deal was done with STP and it became the #20 STP Double Oil Filter entry at the Indy 500. Brushed the wall on 9 May and replaced by the ex-Dallenbach car for qualifying and the race. Presumably Johncock returned to this car for the remainder of the 1974 season. Identified from pictures as the car raced by Johncock on short tracks in 1975. Then sold to Richard Routh and entered for Gary Allbritain as #75 in early 1976 but Allbritain crashed in practice for his first two races and his entry for the Indy 500 was refused. The car was then kept by Todd Gibson as a source of spare parts for the ex-Andretti Eagle that the Routh team bought from VPJ. The left rear corner from this car was removed to repair the ex-Andretti Eagle after Gibson crashed it at Milwaukee in 1977. Subsequent history unknown.
- Vollstedt 72  (Tom Bigelow): New for 1972 as the #27 Vollstedt Enterprises entry for Denny Zimmerman but arrived too late to qualify. Raced by Zimmerman at Pocono and Ontario in 1972 and then retained for 1973 as a backup to the new "bunkbeds" car and raced as the #27 by Tom Bigelow. It was Bigelow's intended #27 car at Indy in 1974 but crashed heavily on the second day of practice. Extensively rebuilt for 1975 with the radiators moved from McLaren-style sidepods to the nose. Bigelow preferred the 1973 car in McLaren form at the Indy 500, but raced the revised 1972 car at the Pocono 500. Used by Janet Guthrie as the #27 in 1976 but then retired. Donated to the Indianapolis Motor Speedway Museum in May 1982.
- Eagle 70  (TBA): Jim Robbins (Troy, MI), of auto parts manufacturer Jim Robbins Co. entered a number of cars during the 1950s and 1960s up to his death in a plane accident in September 1966. His son Jim Marshall Robbins took over the team and for 1970 bought a brand new Eagle, to be prepared by crew chief Bill Spangler. It was entered at Indy for Sammy Sessions as the #67 car and finished 12th. It was also entered later that season at Ontario but Larry Dickson could not qualify it. At this point Robbins Jnr took up racing himself, competing in SCCA racing and progressing later to Trans-Am but was obliged by his father's will to continue to enter a car at the Indianapolis 500. The team's 1968 Eagle was sold but the 1970 car continued to be entered up to 1975, looking increasingly forlorn at each appearance. At that point the Robbins cars were for sale, but a year later the Eagle was back at Indy, now with a 305 ci Chevrolet engine in it, used by Robbins as a protest at the costs of running a car. It was next seen in August or September of 1989 when Canadian racing car dealer Jack Boxstrom purchased the car from someone in Indianapolis, and Steve Kaping went to Indianapolis to pick it up and bring it to Canada. Kaping checked over the car and gave it a brief test at a nearby airport. History then unknown until owned by David S. Morrison (Long Beach, CA) and run in the Victory Lane Historic Champ/Indy Car Showcase in June 2005.
The identification of individual cars in these results is based on the material presented elsewhere in this site and may in some cases contradict the organisers' original results.
The foundation for this research is the work done by the late Phil Harms collating the results of all AAA, USAC and CART races, including the period covered here. His data was refined by Michael Ferner who added more information before making it available to OldRacingCars.com. Since the start of the USAC project on OldRacingCars.com in 2004, a wealth of further information has been gleaned from the Carl Hungness and Donald Davidson Yearbooks, Formula and On Track magazines, USAC News, National Speed Sport News and other published sources. Gerry Measures has also provided much information from his files as have others on TNF and Trackforum. Since 2009, the work of Simmo Iskül and others identifying cars from period photographs has has moved this research forward significantly.
