Notes on the cars:
- McLaren M16A  (Mark Donohue): Roger Penske 1971 for Mark Donohue (#66 Sunoco) at Pocono and Ontario, replacing M16/1 destroyed at the Indy 500. Also for Donohue in the early races of 1972 and probably the #8 backup entry at the Indy 500. It was then sold to George Walther and raced by Salt Walther later in 1972. The Walthers bought other McLarens over the winter and this was retained as an unused backup in 1973. Walther raced it at Trenton in April 1974 and may have used it at other short-track events in 1974 and 1975. For 1976, it was sold to James C Bidwell (Indianapolis, IN) and Robert Bidwell (Lauderhill, FL) and entered as the #36 Shurfine Foods for Jerry Karl after Indy in 1976 and for Jerry Sneva in 1977. To Frank Fiore (#88 Machinists Union) late season 1978 for Tom Gloy; and Ontario only 1979 for Ken Nichols. Then sold to Buddy Boys (Calgary, Alberta) and entered as the #68 at the Indy 1980 for fellow Canadian Frank Weiss to drive, but crashed heavily during practice. The Hungness Yearbook describes the impact as having been on the left front and the car as "extensively damaged", adding that the injured Weiss had to be released using a Hurst rescue tool, the so-called "jaws of life" which could have done significant damage to the monocoque.
- Hayhoe 68 (Billy Vukovich): One of two cars built by Hayhoe Racing Enterprises, this is the car entered as the #59 Cleaver Brooks Spl in 1968. Presumed for now to be the same car used as the #59 on the team's other appearances, but it is possible that the sister car (the #62 at the Indy 500) was used at some events that season. To 3-K Racing Enterprises for 1969 and entered as the #59 Krohne Grain Transport at the Indy 500, but again it is possible that the sister car (the #39 at the Indy 500) was substituted at later short track events. To Jerry O'Connell for 1970 and both cars were entered as Sugaripe Prune Spls at four races that year. Retained for 1971 when Jud Phillips joined as O'Connell's new chief mechanic and run for most of the year with this car now as the #32 Sugaripe Prune entry for Billy Vukovich. Unknown after 1971 but if this was the only survivor, it would be the car raced by Dave Bowling (San Jose, CA) in Northern Auto Racing Club (NARC) Sprint Car Racing in Northern California in 1975. It would also be the basis of his "ecology car", raced in 1977, and probably his rear-engined car in 1974. In 2008 the car was for sale with Chuck Haines (St Louis, MO), restored to its 1971 #32 livery. By 2015, it had been sold to Jim Griggs (Panama City, FL).
- Kuzma-Kenyon 71 (Roger McCluskey): New for the 1970 Indianapolis 500, and fitted with a turbo Ford engine for Wally Dallenbach to use briefly in practice as Lindsey Hopkins' #6 Sprite entry. Chief mechanic Jack Beckley then left the team, and Don Kenyon took over his role. The #6 Kuzma was then presumably the car driven by Mel Kenyon at Michigan in July, and at Ontario in September. The #6 car then became Roger McCluskey's regular Kuzma-Ford during 1971, finishing third at Michigan in July, and second at Phoenix in October. McCluskey drove it at a few short track races in 1972, and it was also his unused spare car at the 1972 Indy 500.
- Kenyon-Coyote (Wally Dallenbach): 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.
- Mongoose 71 (Cale Yarborough): New for Cale Yarborough to race in 1971 as the Gene White team's #21 car. After 1971, this car remained unused and was dismantled but still in exactly the same livery when in the collection of Bob McConnell (Urbana, OH) in 2010. Sold in August 2013 to Brad Edwards (Plainfield, IN) who started a full restoration with a view to having the car on track by May 2016.
- Kingfish 70 (Larry Dickson): Built by Grant King for 1970 and raced by Art Pollard in the early races of the season as his #10 Pollard Car Wash entry. Pollard and King separated after Milwaukee in June, and the car was next seen at Ontario where it was the #41 Grant King entry for Greg Weld. Weld then crashed it in practice at Trenton in October. It returned in 1971, still as the #41 entry, and was driven by Roger McCluskey at Rafaela. George Follmer put it in the race at Indianapolis and it then became the #40 STP entry for Larry Dickson and others later that season, including George Snider. As far as can be determined, this car was Snider's #35 car at the opening race of the 1972 season, and then used by Steve Krisiloff as the #15 at two short track raced later that season. It was then Krisiloff's #24 entry at the opening race of the 1973 season before finally being retired.
- Kingfish 71 (Steve Krisiloff): Built new by Grant King for 1971 but to the same basic design as the 1970 Kingfish. First appeared at the 1971 Indy 500 as the #45 Spirit of Indianapolis entry for Larry Dickson, who qualified. The team was then taken over by Andy Granatelli and the 1971 car became the #20 entry for Granatelli's regular driver Steve Krisiloff for the rest of the season. This may have been Krisiloff's #15 entry at Trenton in April 1972, and was then brought out of retirement for Greg Weld to drive as the #35 at Pocono, after one of the team's 1972 cars had been destroyed. The car then remained at King's workshop until his death in a road accident in December 1999. Shortly after this, the car was sold to Bruce Weatherston (Chicago, IL). It remains in his collection, still in unrestored original condition.
- Mongoose 67 (John Martin): New to the G. C. R. team managed by Jim Rathmann and backed by two US astonauts. Entered as the #71 at the 1967 Indy 500 but crashed in practice by Bobb Johns. Reappeared as Milwaukee later in the year as the #76 for Gary Congdon when it had been converted from Offy to Ford power. Then sold to J.C. Agajanian and entered as the #98 Agajanian REV 500 for Billy Vukovich at Riverside at the end of the season. Retained as the #98 entry for Vukovich through 1968 except at the Indy 500 where it was the #97 entry for Gary Bettenhausen. Retained again for 1969, again as the #98 for Vukovich when it was used with Ford, Offy and Chevrolet engines. Retained again for 1970 but now as the #97 entry as the Agajanian team had a new Wolverine car as the #98. It appeared yet again in the middle of 1971, when it was raced twice by John Martin as the team's #97 entry. Then unknown until it was bought from Bob Jongbloed by an unknown owner as a "Brabham" but still wearing a USAC registration tag '71 - 97'. Identified by Dave Laycock from photographs as a 1967 Mongoose. Sold it 2012 to Butch Gilbert (Westley, CA) who started a restoration of the car to its 1969 livery.
- Eagle 66  (Johnny Rutherford): A customer car sold to John W. Klug (Newport Beach, CA) of Pacesetter Homes, fitted with a 255ci Ford V8 and entered at the 1966 Indy 500 as the #88 Bardahl-Pacesetter Homes Special for Jerry Grant to drive, with Roy Campbell as chief mechanic. Klug's USAC entry form identifies the car as chassis 203. Grant was dropped by AAR's team of Can-Am Lola T70s at the beginning of October 1966, and set up Friedkin Enterprises Racing Division with financial backing from his old friend Tom Friedkin (San Diego, CA), and with ex-AAR mechanics Larry Stellings and Larry Webb. The new operation had two Eagles, Grant's #88 Indy 500 car chassis 203 which Friedkin acquired from Klug and the former Yamaha #6 car of Joe Leonard, and acquired a new Lola T70 which Grant drove at Riverside in October, entered by Alan Green Chevrolet. Grant drove the #88 Eagle at Phoenix in November as a Bardahl entry and this is presumably the #78 Friedkin Enterprises entry for Grant at the 1967 Indy 500 and at road course events later in the season. It was entered by Friedkin Enterprises as the #76 for Jerry Titus at the 1968 Indy 500. No sign has been found of it racing again in 1968, but photographs show that this was the car used in the Universal Pictures film 'Winning', starring Paul Newman and filmed during the summer of 1968, where it appeared as the #42 car of Robert Wagner's character Luther Lou Erding. It was then sold to Jackson oilman Walt Michner for his Michner Petroleum team, and used by driver Johnny Rutherford as a backup to his 1967 Eagle. The 1966 car was fitted with an Offy turbo for 1969 and entered as the #36 Patrick Petroleum car for Rutherford throughout the season. Retained by Michner for Rutherford during the 1970 and 1971 seasons still in partnership with Michner's 1967 Eagle as the #18 entry. The 1966 car was nicknamed "Geraldine" during this time and the 1967 car "Old Shep". Then to Marvin Webster (who had previously owned 'the AAR/Leonard car') and on the entry list at Ontario in 1972 for Don Brown. Next seen in practice at the 1973 Indy 500, entered by Webster as the #76, and later at Ontario in September 1973 where John Cannon raced it. Advertised by Webster in December 1973 with a 1968 Eagle. Unknown until owned by Anthony Seibert (Boulder, CO) in May 1983. Reappeared when sold by Joseph D Lhotka, Trustee, Shawn S Trust (Westminster, CO) to Centennial Import Motor Co (Boulder, CO) in April 1987, and then sold almost immediately to Chuck Haines (Manchester, MO). Retained by Haines until 2005, when sold to Aaron Lewis (Cessnock, NSW, Australia) and restored to Rutherford #36 livery. Run at the Phillip Island Classic 2011 by Lewis, and displayed car at Indianapolis in 2017 and 2018. Sold to Bobby Rahal (Chicago, IL) in October 2018.
- Gerhardt 66? (Jerry Karl): ARDC midget owner Ken Brenn Sr (Warren, NJ) ran a #57 Gerhardt for Bob Harkey in 1967 (also driven by Lothar Motschenbacher at Phoenix) and then ran a #88 Gerhardt in 1968 for a variety of drivers. According to Gary Mondschein, these were two different cars, the first being a '66 car and the second a '67 car, and Brenn told him both cars came from Goodyear and were unraced. Simmo Iskül's analysis supports them being two different cars, but shows that both were 1966 Gerhardts. Brenn's 1967 car went to Bulldog Stables for 1968 and would be the #36 Gerhardt-Chev run on the USAC trail in 1968 and the #68 in 1969 for drivers such as Gene Bergin, Bob Harkey and Denny Zimmerman. It was joined by a Gerhardt-Offy towards the end of 1968 and the team ran both cars a few times early in 1969. The ex-Brenn #68 then reappears as Jerry Karl's Trackstar Helmet entry (photos in the Hungness yearbook 1969 p41 and 1970 p103 show the car almost unchanged) becoming his #52 entry in 1970 and presumably his #102 Winters Transmission entry in 1971. It was then sold to Geoff Bodine who added a roll-cage and set it up as a Super-Modified and raced it at Oswego Speedway (near Syracuse, NY) in 1972, taking a fourth place finish in a race on 3 June 1972. The car was later in the collection of Bob McConnell (Urbana, OH), still unrestored in Bodine's colours. Sold to Gary Mondschein in 2011 and was being restored in 2014 by Walt Goodwin.
- McNamara T501 ['2'] (Mario Andretti): New for Mario Andretti as the #5 STP entry at the 1971 Indy 500. Andretti qualified ninth with a speed of 172.612 mph. The car was damaged during the race when Andretti spun on oil and hit the barrier but was rebuilt extensively by chief mechanic Jim McGee in time for Pocono in July. Andretti qualified fifth and finished fourth at Pocono, then also raced this car at Michigan two weeks later, where he qualified third but retired, and at Milwaukee in August. Andretti used a newer long-chassis car produced by McGee at Ontario, but returned to the Pocono car for the final two races of the season at Trenton and Phoenix. He took second place at Trenton, the best result by this model of McNamara. The 1971 McNamaras were not used again, and McNamara prepared for the 1972 Indy 500 was a 1970 car. Subsequent history unknown.
- Gerhardt 68/69 (Jim Malloy): A late-1968-style Gerhardt that first appeared as part of the Federal Automotive team at the 1969 Indy 500 as the #31 Federal Engineering entry for Bobby Johns. Johns did not qualify and Bud Tingelstad took over the #31 for the rest of 1969. This car returned to Indy in 1970 as Federal's #31 Stearns Transi-Tread entry with Paul Brooks as chief crew for driver Jim Malloy who qualified. The 1969 car is presumed to be the #31 car from then until the team disappears at the end of 1971. Subsequent history unknown until Hurricane Charley in August 2004 damaged a building in Florida, revealing the little-known car collection of real estate developer Walter Medlin. The #31 Gerhardt, in apparently original condition, was visible in pictures of the damaged building. In April 2007, the car was pictured on an open transporter on Interstate 65 heading north of Nashville, TN. With it were the 1979 Cicada and an unidentified #99 car. Rumoured to be in a private museum in Indianapolis (and the I-65 through Nashville is exactly on the route from Florida to Indianapolis).
- Eagle 67  (George Snider): Sold to the Jud Phillips half of the Leader Card team, fitted with a Ford V8 and entered for Bobby Unser as the #6 Rislone car from the start of the 1967 season. In 1968, this car was used by Unser on ovals, helping Unser to the USAC title, together with a second 1967 Eagle used for road racing and a 1968 Eagle with which he won the Indy 500. Retained again for 1969, but only raced Unser at Dover Downs. However, after his other 1967 Eagle was wrecked, this original car was used by Unser on ovals in 1970, with the 1968 Eagle being used on road courses. Unser and Phillips both left Leader Card Racers later in 1970, and their equipment was transferred to the AJ Watson half of the Leader Card team. The 1967 Eagle was raced by Watson's driver Mike Mosley to win at Trenton in April 1971, and by George Snider at five later races. At some point, this car was damaged, and the unrepaired monocoque was given by Watson to Bentley Warren, who was racing the ex-Michner 1967 Eagle. It was still unrepaired when bought from Warren by consortium "Eagle Partners" who restored the ex-Unser car and sold it in July 2005 to Aaron Lewis (Cessnock, NSW, Australia). Sold by Aaron in 2014 to Scott Borchetta (Nashville, TN), the founder of Big Machine Records, who ran it in the vintage event at Indianapolis in May 2015.
- Lola T152 2WD [SL150/3?] (Dick Simon): New to Roger Penske, in December 1968 according to Lola records, although it has been claimed that Penske's car was a rebuild of a car that raced some time in 1968. The car would be driven by Mark Donohue, who was also driving Penske's Lola T70 in sports car racing, and both Lolas used Chevrolet engines. The T150 did not run at the Indy 500, where Donohue used a brand new T152 instead, and was a non-starter at IRP in July. Donohue was seventh and fourth in two races at Brainerd in September, but retired at Seattle and Riverside. The car was fitted with a turbo Ford for testing at the start of 1970, but used a Chevrolet engine when raced at Sears Point and IRP. Sold to Dick Simon for 1971, and raced with a turbo Ford engine as the #10 TraveLodge Sleeper entry. Also used at Milwaukee in August 1972, when Simon focused on his new 1972 Peat-Lola, and possibly at other short track events. The car reappeared in 1976 when Greg Hodges (Indianapolis, IN) attempted to qualify it for several short-track Indycar races, without success. The car then had a Chevrolet engine, and still had the bulbous sidetanks seen when Simon had raced it in 1971. Subsequent history unknown, but some time around 1982 the car was in the collection of Dieter Holterbosch (Cove Neck, NY), a well-known collector of cars who died in July 2016 age 95. It was for sale from the collection at the time for $12,000.
- Scorpion 71 (Art Pollard): The Scorpion that was Art Pollard's intended #8 car at the 1971 Indy 500 was then Jimmy Caruthers' car at the 1972 Indy 500 (although Hungness 1972 allocates Pollard's start to it). It seems likely that this would then be Pollard's #8 car after the 1971 Indy 500 at least up to the crash at Michigan. It is also presumed to be Caruthers #11 car after the 1972 Indy 500 up to his major accident at the Pocono 500. Caruthers crashed into the outside wall at turn 3, and was taken to hospital with burns and contusions. The team did not appear again. The Pocono wreck was later repaired and was owned by Doug Winslow (Westlake, Ohio) in June 2015.
- Coyote 70? ['70-1'?] (AJ Foyt): New for AJ Foyt at the 1970 Indy 500 as the #7 Sheraton-Thompson entry. Also raced by Foyt at Milwaukee in June, but he used an older 1969 car on short tracks later in the season. Believed to have been Foyt's car at Ontario and Phoenix later in the season. It was then retained for short tracks in 1971, so was probably Foyt's car again at Phoenix in early 1971. It was also his car at Michigan in July, probably at the June Milwaukee, and possibly at other tracks. It may have been Donnie Allison's car at Ontario in September. In 1972, the car was sold to Lee Brayton, to replace the 1969 car that he had wrecked in Indy 500 practice. Raced by Brayton later in 1972, at one race in early 1973, and even at two races in early 1975. It was eventually acquired from Brayton by a sponsor, Harry Oppenhuizen, and was sold by Oppenhuizen to Bill Wiswedel (Holland, MI) in 1988. Owned by Wiswedel and then his son, also named Bill, ever since.
- Eagle 71  (Bobby Unser): New for Bobby Unser to drive at the 1971 Indy 500 as AAR's #2 Olsonite entry. As the sister car was wrecked by Lee Roy Yarbrough at the Speedway, this is likely to be the 1971 Eagle raced by Unser at Pocono, Michigan, Ontario, Trenton and Phoenix. For 1972, the car was sold to a consortium led by James C Rogers that entered it as "The Minnesota Invader" for Larry Dickson (Marietta, Ohio) to drive, with sprint car builder Paul Leffler (St Paul, Indiana) as chief mechanic. It did not qualify after Leffler claimed that the money needed for a new engine did not turn up from "the Minnesota people" and the car was not seen again that season. Leffler and Dickson focused instead on their successful USAC Sprint campaigns. In April 1973, Rogers and his associates sued Leffler who they claimed had retained the Eagle. The car then found its way into the ownership of Greg Hodges (San Francisco, CA). Photographs of the car in 1974 or 1975, show it in virtually identical configuration to when Dickson drove it at Indianapolis. This is presumably rhe 'Eagle' that Hodges raced at Mosport Park in 1976, but photographs of that car remain elusive. Subsequent history unknown but at some point acquired by Gary Schroeder (Burbank, CA) and restored by Phil Reilly & Co. to its original Unser #2 livery. It won Best in Class at the Amelia Island Concours in 2004 and was part of the Victory Lane Historic Champ/Indy Car Showcase at California Speedway in January 2005. By 2010 the car was on display in the NHRA Motorsports Museum. In March 2012, the car was on display in the Riverside International Automotive Museum. By March 2017, it had moved again, and was on display at the Petersen Automotive Museum in Los Angeles.
- Colt 70 [002?] (Joe Leonard): A second 1970 Colt built for Joe Leonard to drive for Vel's Parnelli Jones Ford as the #15 Johnny Lightning 500 entry. Leonard only used the car at the Indy 500, Milwaukee in June which he won, and Ontario in September. As Al Unser didn't get his Colt 71 until the Indy 500, we can be confident that Leonard was also driving a Colt 70 in the early races of 1971, presumably his regular 1970 car. Leonard then used his new 1971 car at the Indy 500, at Milwaukee in June, and at Pocono, but at Michigan in August he was back to an older car, presumably this 1970 car. After damaging that car against the wall at Michigan, he was said to be driving Unser's 1970 short track car (i.e. an updated Lola) at Milwaukee in August before returning to his new 1971 car for the last three races of the season. Subsequent history unresolved.
- Morris Marauder (71) (David "Salt" Walther): According to Bob Sawicki who talked with Jeff Walther at the Walther Auction, the Walthers bought a car from George Morris for the 1970 season, and then had two more built for the 1971 season. The main 1971 car was the #77 entry at the 1971 Indy 500 and it is assumed that this car was used for the rest of 1971 and in early 1972. This car, still unrestored and carrying USAC tag "#C-71 177", was sold at auction at Auburn in June 2012 to Doug Winslow (Cleveland, OH). Sold in July 2015 to Mark Klingerman (Bourbon, IN) and Gary Berkey (Warsaw, IN). Restored and appeared at the Historic Indycar Exhibition in May 2016 and in May 2017.
- Mongoose 71 (Lloyd Ruby): 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".
- Gerhardt 70 (Gary Bettenhausen): New for Gary Bettenhausen for the 1970 Indy 500 as the Gerhardt team's #16 Thermo-King entry, where he qualified 20th and retired early. He used this car at Milwaukee eight days later, but then used one of his 1969 cars for much of the summer before racing his Indy 500 car again at Ontario in September, Trenton in October and Phoenix in November. He raced it again at Rafaela in February but then used the heavily modified sister car at Phoenix and Trenton. This car was modified along the same lines for Bettenhausen to use at the 1971 500. It was then modified again, this time along McLaren M16 lines, for Bettenhausen to race at Pocono in July, Michigan in August, Ontario in September, and Phoenix in October. It was then Jim Malloy's #16 entry at the start of the 1972 season, then the #46 car at the 1972 Indy 500 that was changed to run as #16 for Jerry Karl after Malloy's crash in the team's new Eagle. Johnny Rutherford then took over the car at Milwaukee in June but consumed in a "fiery and spectacular crash".
- McLaren M15A  (Gordon Johncock): Chris Amon's planned car for the 1970 Indy 500 was taken over by Carl Williams when Amon withdrew. It was sold to Gordy Johncock after the 500 and became his main car after M15/2 was wrecked at Michigan. Sold to Rolla Vollstedt for 1971 and raced for him by Johncock and Denny Zimmerman in 1971 and 1972. This car was later acquired by Tom Black (Portland, OR) and sold by him to the UK. Believed to be the car acquired from collector Nick Mason by McLaren International, restored and put on display in the Donington Collection.
- Colt 70 [001?] (Al Unser): A brand new car fabricated by George Bignotti's crew for 1970, and raced by Al Unser for Vel's Parnelli Jones Ford as the #2 Johnny Lightning 500 Special. Unser dominated the 1970 Indy 500 in this car, and he also raced it at four other races later in the season. This is believed to have been Unser's car for the early 1971 races, winning three of them. It was then the backup car that Unser drove at Pocono and Michigan in July, and at Milwaukee in August, where it was wrecked. The car was retired, restored to its 1970 colours and used as a show car, later spending many years in the VPJ Collection's private museum in Torrance, CA. It returned to the Speedway for a race day celebration in 2010, and was acquired by the IMS Museum in May 2012 together with the rest of the VPJ Collection.
- Eagle 68  (Arnie Knepper): 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 not seen in 1970, but then went to Arnie Knepper and became his #90 C.H.E.K. Racing entry in 1971 and 1972, and finally his #45 entry at the 1973 Indy 500. It was then the LaWarre Precision Eagle entered by Robert W. LaWarre Sr (Titusville, FL) for Larry Rice and John Hubbard in 1974 and 1975. The Eagle was then retired but remained in LaWarre's ownership until his death in April 1997, after which 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.
- Vollstedt 66  (Denny Zimmerman): Built for 1966 and raced by Billy Foster as the #27 Jim Robbins entry. Retained for 1967 and intended to be raced by Lucien Bianchi in 1967 but borrowed by Mario Andretti for the opening race of the 1967 season, only to crash it in practice. Bianchi was later bumped at the Indy 500. Raced by Jim Malloy for the rest of 1967 and for occasional races in 1968 and 1969. To Frank J Fiore's Fiore Racing Enterprises for 1970 and raced as the #43 by Bob DeJong and then in 1971 by Denny Zimmerman. Later entered by Fiore as the #43 again for Al Loquasto in 1972, Jerry Karl and Bob Harkey in 1973, and Karl Busson in 1974. Later sold by Fiore and the car passed through several collectors until purchased by the Fiore family in 2001. Fiore died in 2007 but his son Frank Fiore Jr (Dallastown, PA) continued with the car's long-term restoration. The car appeared in public for the first time in 45 years at the Vintage Celebration at Pocono Raceway in August 2017.
- Philipp 64 (Larry Cannon): This car was originally built by Bob "Rocky" Phillip in Culver City, CA as the Rose Trucking Co.'s #10 rear-engined Offy entry for the 1964 Indy 500 to be driven by Ebb Rose. It was used in practice by Johnny Rutherford, running as a Racing Associates entry, but no attempt was made to qualify it. It was raced by Rutherford at Sacramento in October with a Chevrolet engine and then again at Phoenix (as the #24) at the start of 1965 with an Offy again. Rose drove it in practice for the 1965 Indy 500 where it was the #79 but crashed during practice. What happened next is unknown, but an article in the Decatur Daily Review in April 1970 revealed that the car had been bought by Richard 'Unk' Blacker (Champaign, IL) and repaired. Blacker then fitted a Chevrolet engine and entered it for supermodified driver Larry 'Boom Boom' Cannon (Danville, IL) in 1970 Indy racing as the #47 Autotron Photoelectric 'Blacker-Chevrolet'. After two failures to start a race early in the 1970 season, Cannon then crashed the car during practice for the Indy 500. He qualified for a couple of short track events later in 1970, and then joined the trip out to Argentina for the Rafaela race in early 1971. After two more failures to qualify later in 1971, the car was not seen again. Blacker, a former owner of Unk's Tavern in Champaign, died in 2002, aged 82. Cannon died in 1995. Nothing more is known of the history of their car.
- Eagle 67  (Bill Simpson): The #74 AAR entry for Dan Gurney at the 1967 Indy 500, fitted with a Ford V8 and with support from Wagner Lockheed. Sold after the race to AJ Foyt and photographs show that it was the car raced by Joe Leonard at Mosport Park in July 1967, still in works livery. The history of the car over the next three years remains unknown but according to the Hungness Yearbook, it reappeared at the 1970 Indy 500 still as part of the Foyt team but now equipped with a turbo Ford and entered as the #83 Greer car for Donnie Allison, who finished fourth. Then sold to Bill Simpson (Los Angeles, CA) and raced by him with a Chevrolet engine and three late-1970 races. Fitted with an Offy turbo for Simpson in 1971 and 1972. Sold to Marv Carman (Union City, Michigan) and turned into a supermodified, but at some point the car was very badly damaged in a workshop fire. The remains of the car were acquired by Richard Bible and they were stored until 2008, when bought by Indycar collector Bill Wiswedel (Holland, Michigan). In 2012, Wiswedel sold the fire-damaged tub and its surviving components to Justin Gurney, son of Dan Gurney and then CEO of AAR. He sent the tub to John Mueller and Jerry Wise of Entrepreneur's Motor Sports (Fresno, CA), who built a completely new car to take its place, there being no part of the damaged tub that was usable. The new car was unveiled on Dan Gurney's 84th birthday in April 2015.
- Morris 69 (Bill Puterbaugh): New to the MVS team, fitted with a Ford turbo engine and entered at the 1969 Indy 500 for Arnie Knepper to drive as the #29 MVS Special. The new car went very well during the practice month and Knepper qualified comfortably, but crashed out of the race. After four more races in the Morris-Ford, Knepper was replaced by Sam Sessions, who finished fourth at Trenton in September. The Morris was largely a backup in 1970, but was raced regularly during 1971, by Jim Malloy early in the season and by Bill Puterbaugh later on. Subsequent history unknown.
- Colt-Lola T150 [SL150/2] (Sammy Sessions): New to Al Retzlof for his Retzloff Racing Team, prepared by George Bignotti and entered at the 1968 Indianapolis 500 as the #5 Retzloff Chemical car. The car was in two-wheel drive specification for this race, with lead driver Al Unser also having SL150/1 available in 4WD specification as the team's #24 entry. Unser damaged SL150/2 in practice, and raced SL150/1, leaving teammate Carl Williams out of a drive. The car was returned to England for repairs, and was returned in time for the twin races at Indianapolis Raceway Park, both of which Unser won, with the car now in 4WD specification. He also raced it in the twin races at Mont-Tremblant two weeks later, but crashed in the second race and severely damaged the rear suspension. Unser raced it several more times that season. The team was transferred to Parnelli Jones and Vel Miletich's Vel's Parnelli Jones Ford team (Torrance, CA) for 1969, including both Unser and Bignotti, and this car was Bud Tingelstad's #15 drive at the 1969 Indy 500. It was then raced by Jim Malloy and Unser later that season, but its exact usage in 1969 is still to be resolved. In 1970, it was retained by the team, modified along the lines of Bignotti's new Colts, and won four races as Unser short track car. For 1971, it was sold to Agajanian Faas Racers, and raced as the team's #98 entry by Sammy Sessions. When Agajanian and partner Leonard Faas separated, Faas kept the car and it became his #11 King O'Lawn Special later that season. In 1978, it was sold to Milt Jenson, and in 2000 he sold it to Michael & Danna Huntley-Lashmett. They sold it to Harvey Cluxton in 2002, and it was then sold to a Nevada car museum which closed in 2007. It was then sold to Bill "Speedy" Smith for his Speedway Motors Museum in Lincoln, NE.
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.
