Notes on the cars:
- McLaren M16A  (Roger McCluskey): McLaren Cars at the 1971 Indy 500 for Peter Revson (#86) and qualified on pole at the Indy 500, finishing second. Probably the #86 car used by Gordon Johncock at Trenton 1972 and the #86 entry that did not arrive at the Indy 500. Then sold to Lindsey Hopkins for Roger McCluskey for the rest of 1972 as the #14 American Marine entry, winning at Ontario. Retained for 1973 as the #3 Hopkins Buick entry and used by McCluskey at Indy and Pocono, before settlig on his newer M16B thereafter. The older M16 was then unused and had been stripped down to a bare monocoque by the time it was sold to John Martin in mid-1975. He used the tub to rebuild the M16B that he had crashed at Milwaukee in June 1975, and the resulting car used the chassis plate and identity of the M16B.
- 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 [7207?] (Billy Vukovich): One of two 1972 Eagles, the other being 7204, bought new by Jerry O'Connell's Sugaripe Prune team and raced by Billy Vukovich as the #3 entry in 1972, with Jud Phillips as chief mechanic. This car can be identified from an invoice later in its life so is known to Vukovich's backup car at the 1972 Indy 500 (entered as #32 but ran as #3 and crashed during practice) and then became his long track car later in the season. Finished second at the 1973 Indy 500 and won at Michigan the following August. The team then bought a 1974 Eagle and sold 7204 but kept this car as a backup for three more seasons. Sold to Arthur E. 'Art' Sugai (Ontario, OR) for 1977 and entered as the #91 Eastside Café car that season, alongside the ex-Penske 7225. Sold with 7225 to collector/dealer Chuck Haines (St Louis, MO) in May 1980 and fully restored to 1972 specification by Walter Goodwin of Race Car Restorations. On display for many years at the "International Motorsports Hall of Fame", a NASCAR museum at Talladega Speedway in Alabama.
- Eagle 72  (Lloyd Ruby): Bought by Firestone for Lloyd Ruby and his chief crew Mike Devin to run as part of Gene White Racing in 1973, but Firestone withdrew support from White before the end of 1972. Ruby and Devin were passed initially to Bruce Crower and then to Vel's Parnelli Racing before they were put together with Mike Slater, President of Commander Motor Homes, in time for the 1973 Indy 500. Ruby raced 7224 as the #18 Commander Motor Homes entry in 1973, but wrecked the car at Ontario in September. Devin acquired a new monocoque numbered 7228 and built that up as the team's race car. The 7224 monocoque was repaired and sold with the complete 7228 car to Anastassios "Tassi" Vatis, a Greek shipping tycoon and veteran Indy car owner. The complete 7228 was run by Vatis's faithful chief mechanic Bill Finley for Johnny Parsons Jr in 1975, but for 1976 the team had a "new" car built on an "unused" chassis. As this car carries the 7224 plate today, it must be the rebuilt Ontario chassis. It was raced by Parsons as the #93 Ayr-Way/Vatis entry in 1976, then for 1977, it was heavily modified by Finley, with narrower sidepods, presumably using the 1976-spec 20-gallon fuel tanks, and main radiators repositioned to the rear of the tub. It was again the #93 Vatis entry at the 1977 Indy 500, where Steve Krisiloff crashed on his qualifying run. As far as can be determined, it was Bill Vukovich's #93 Vatis entry in 1978, when he was unable to find enough speed to qualify. John Mahler (Bettendorf, Iowa) then bought the Vatis team and it is believed that 7224 was the #92T car that Mahler raced at the 1979 Indy 500 after his intended #92 race car was bumped. Sold to motorcycle speed record holder Don Vesco (San Diego, CA) and raced at Willow Springs in 1981. Then to Ron Blondel (Ontario, CA), but the car was in pieces during his ownership. To Floyd Sable (Anaheim, CA) in 2003, and restored between 2004 and 2009 to Mahler's 1979 specification. Run at the Indy 500 parades in 2012, 2013 and 2014. Sold to Mick Anderson (New Richmond, Wisconsin) in July 2014.
- Eagle 72  (Wally Dallenbach): 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 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.
- 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 and sold it to Dave Hammers (Sea Cliff, NY) around 1988, and he sold it to Bill Wonder (Glen Cove, NY) in 2011. Wonder died in January 2022 at the grand age of 98, and his cars are due to be auctioned by Gooding & Company at its Pebble Beach auction in August 2022.
- 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).
- Eagle 72  (Mike Mosley): New to Leader Card Racers in time for the 1973 Indy 500 where it was Mike Mosley's #98 Leader Card entry. Raced by Mosley at Pocono and at Ontario, and then at the late-season races. Presumably his car at Ontario in March 1974, after which he used a new 1974 Eagle, and this 1972 Eagle was not seen again in 1974. After the 1974 car was wrecked, this car reappeared for Steve Krisiloff at Ontario in March 1975 as the #98 entry, then for George Snider as the #97 at three more races. Taken to the 1976 Indy 500 as a backup and qualified by Tom Bigelow, and may have been used by Bigelow at some short track races that year as the #24 entry. Although Leader Card now had two 1974 Eagles, this old 1972 car was present at the Indy 500 again in 1977 as the #23 entry but was crashed heavily in practice on 16 May by Gary Irwin and "damaged extensively". Repaired and then acquired by Warner Hodgdon, who had sponsored Mike Hiss in Leader Card's '74 car in 1976. Retained by Hodgdon until his death in 2013, and acquired from the estate by Jeff Urwin (New York, NY). The car was inspected at GE Autosport's shop at Indianapolis in November 2014 by Jacques Dresang, who found traces of Leader Card livery and USAC stickers that tied it to Gary Irwin's 1977 Indy 500 entry.
- Eagle 72  (Sammy Sessions): 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.
- Eagle 72  (Lee Kunzman): 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.
- Coyote 73 ['73-2'] (AJ Foyt): New for AJ Foyt at at the 1973 Indy 500 as Foyt Enterprises' #14 Gilmore Racing entry. Photographs show that it was also raced by Foyt as the #14 at Pocono, Michigan in July, Ontario, Michigan again in September, and Trenton in September. It is likely to be the car raced by Foyt at Texas World Speedway in October and by George Snider at Phoenix in November, but this remains unconfirmed. The side-radiator 1973 Coyotes were not seen again after 1973 and were presumably rebuilt into the team's front-radiator 1974 cars.
- 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.
- 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.
- 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.
- Coyote 72 ['72-1'] (Dick Simon): 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.
- Kingfish 73 ['1'] (Steve Krisiloff): 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 (Jimmy Caruthers): 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.
- Eagle 73 [7304?] (Bobby Unser): New for Bobby Unser at the 1973 Indy 500, as AAR's #8 Olsonite entry. Unser qualified second but retired at mid-distance. He then drove the same car at Milwaukee in June, winning from pole position. The car Jerry Grant had raced at the Indy 500 was sold to Patrick Racing, leaving Unser with 7302 and the new 7304. Exactly how these cars were used in 1973 is still being resolved but, for now, it is assumed that 7302 was the car he heavily damaged at Milwaukee in August, leaving him with just chassis 7304 to the end of the season. In the final race, at Phoenix in November, Unser destroyed his car in a massive accident. Autosport reported that this car was repaired and sold to the VPJ team, but photogarphs show that VPJ had new 1974 cars from the start of the season, so it seems likely that 7304 ended its life at Phoenix.
- Kingfish 72 ['2'] (Tom Sneva): 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.
- McLaren M16C  (Gary Bettenhausen): 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.
- Eagle 72 [7216?] (Mike Hiss): 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.
- Atlanta 72 (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.
- Mongoose 71 (John Hubbard): 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".
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.
