Notes on the cars:

  1. McLaren M10B [400-10-2] (Frank Matich): New to Frank Matich (Australia) and fitted with Repco's new Holden V8 F5000 engine for Australian racing. Raced for the first time at Warwick Farm on 12 July 1970 but crashed, and rebuilt on a new tub as "M10C". Next raced at Calder on 18 Oct 1970, then at Australian Grand Prix 22 Nov 1970. Raced in the 1971 Tasman series, then to the US for the L&M series before returning to Australia for the 1971 Gold Star series. Crashed prior to Oran Park 27 June and rebuilt on third tub. To Frank Radisich at the end of 1971 and raced in the 1972 Tasman series, the 1972 Australian Gold Star, and the 1973 Tasman. To Keith Laney (NZ), fitted with a Chevrolet V8 and appeared in the Tasman series in 1974 and 1975. Then to Dennis Phillips for hill climbs 1976, then Russel Greer (Blenheim, NZ) and fitted with a 6.3-litre Chevy to win the 1979/80 NZ hill climb championship. Sold to Peter Addison (Australia) but history then unknown until acquired by Max Warwick (Australia) in the mid-1990s. Raced at Historic Sandown from 1998. Sold to Graham Wadsworth (Melbourne, Australia) 2006.
  2. Lola T192 [HU19] (Brett Lunger): New to Roger Penske for Mark Donohue to drive in the 1970 US series, starting at Mosport 13 Sep 1970. To Competition Research & Development (Pomona, CA) for Brett Lunger US 1971, then to Larry McNeil US 1972, US 1973 and then in SCCA Nationals from 1974 to 1978. Via Alan Marvin to Gordon Close (Hinsdale, IL) 1979, and used it for 1979 SCCA drivers school and Regionals. To former racer Don O'Sullivan (Perth, Western Australia) in 1983 but not run by him and sold to Bob Harborow (Camberwell, Victoria, Australia) in 1989. Restored and used in historic racing in Australia, including VHRR Historic Sandown and Phillip Island Classic 1999-2013, and the Australian GP support races in 2009 and 2010. Reappeared in October 2015, when run by Kieran Patel (Victoria, Australia) at the Baskerville Historics. More information about Lola T192 HU19
  3. March 71BM [3] (Max Mizejewski): New to Chuck Willis's CRW Racing (Anaheim, CA) and leased to Jean de la Bruyere (Edmonton, Alberta, Canada) for Max Mizejewski (Woodland Hills, CA) to race in SCCA Formula B in 1971 as "The Edmonton Flyer". De la Bruyere then split from CRW and Ron Dykes (Marina del Rey, CA) then took over the 71Bm for Pro Formula B races and SCCA Nationals for the rest of 1971. Sold to Bob Newton (Cupertino, CA) and run in Pro FB and SCCA Nationals in 1972, 1973 and 1974. It was also raced by Craig Fraser (Santa Cruz, CA) in 1973 and 1974 before Newton's last known appearance in it in late 1974. To Jim Van Horn (Orange, CA) and raced in Cal Club Regionals in late 1975. Van Horn bought a newer Chevron B27 for 1976, but returned to the March for 1977, which was rebuilt to 76B specification by Marc Bahner and fitted with a BDA engine. The car was registered with the SCCA in September 1977, but curiously used the chassis number of a March 722, 722-38. Van Horn raced this car up to 1980. To Bill Hill (Olympia, WA) in 1981, fitted with a Mazda engine and a sports car body and raced the car in SCCA ASR and in Can-Am as the "Marzda" or the "Banana Crate". Crashed in an SCCA Regional (NW Region) at Olympia Airport in September 1986. Hill then bought a Lola T360 and the March chassis stayed in the rafters of his garage for many years. After Hill died, the car was sold to Phil Creighton (Georgia) in mid-2017, and then by him to Kevan McLurg (Brighton, UK) in 2018. Sold to Bruce Balchin (Southampton) in July 2019.
  4. Lola T142 (Don Inferrera): See full history: Lola T142 'the Dave Heinz car'.
  5. LeGrand Mk 7 [002] (Chuck Elliott): A new car replacing the original works Mk 7 sold to Don Richardson, and shaken down by Bruce Eglinton at Whitman stadium June 1968 where he crashed and was badly burnt. The car was rebuilt and loaned to Jerry Entin, fitted with his Chevrolet engine and ZF gearbox, and taken to Road America for the Badger "200" on 27 July 1968, but the timing gear broke before the race, and Entin did not start. Entin won a National at Riverside in August and two Regionals later in the year. Dick Guldstrand took over the car for the Laguna Seca 'Pro' race in October and it was then driven by Rex Ramsey at the ARRC, and at the Monaco International Trophy in New Zealand at the end of December. Ramsey continued to drive the car in 1969, winning three SCCA Nationals but was well off the pace in Pro races. It was then shared by Chuck Elliott and Bruce Eglinton in SCCA Regionals and Nationals respectively in 1970 and 1971. Then sold to Mal Patterson (San Jose, CA), who entered it for the Pro race at Laguna Seca 7 May 1972, but does not appear to have raced it very often. It was then sold to Ken Owen (Union City, CA) and used in local SCCA racing in 1975 and 1976. Then sold to Skip Pack (Hollister, CA) and Dennis McLaughlin , who autocrossed the car in the late 1970s and early 1980s before they sold it to Butch Gilbert in October 2009. Sold to John F Boxhorn (Mukwonago, Wisconsin) in October 2010, and restored during 2011 and 2012. Sold to David Zavetsky (Wellesboro, PA) in 2019. See full history: LeGrand Mk 7 002.
  6. Lola T142 (Len Guneau): Len Guneau (Hermosa Beach, CA): first seen winning FA class in SCCA Regionals at Laguna Seca on 12 Oct 1969, then at Riverside two weeks later, so possibly second hand but there are no obvious contenders except the cars crashed at St Jovite. If new, then likely to be one of the last three Haas cars (43, 44 or 45). Raced at Sebring 1969, the West Coast races in 1970 and at Laguna Seca 1971. On the entry list for Laguna Seca 1972. Subsequent history unknown.
  7. Lola T142 (Mel Andrus): Dick Simon (Salt Lake City, UT) US 1969 (yellow #66 from R1) - (maybe with Hayes 10 Dec 1969?). In the book "The Boys of Indy" (Phil Berger & Larry Bortstein, 1977), Simon is quoted as saying the car was "used". But he also says he won one race (true) and finished in the top six five times in his six races (not so). Simon used this season to get into USAC. Maybe to Hayes. Then to Mel Andrus (Salt Lake City, UT): US 1970 (two races: R2 Edmonton 24 May and R5 Sears Point 28 Jun); US 1971 (only appeared at R1 Riverside 25 Apr: crashed in practice and Andrus was killed). The car was stripped and the remaining damaged section of the chassis lay in a wrecking yard for many years.
  8. LeGrand Mk 11 (Jim Paul): Raced by Rex Ramsey in late 1969, winning at Trois-Rivières in September, but well off the pace in the L&M series. Jim Paul raced the car in 1970, with a best result of eighth in the Pro race at Laguna Seca, and appeared a few times in 1971 and early 1972. To Keith Saunders (Albuquerque, NM) for SCCA racing later in 1972, then to Bill Swope (Albuquerque, NM) for 1973. Swope advertised it late 1975, and it seems likely that this was the LeGrand used by JB Walton in SCCA Regionals in Utah Region in 1978. The next time it was seen was when Harold Janke owned it in Nebraska in the late 1990s. To Kirk Severson and racing in historic events by 2001. To Marty Fidrich (Elisabeth, CO) by 2007.
  9. McLaren M10A [300-02] (Gregg Peterson): See full history: McLaren M10A 300-02.
  10. McLaren M10A [300-05-2] (Jon Milledge): See full history: McLaren M10A 300-05.


Note that 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' published results.

1968 US information has been taken from SCCA results sheets with additional information from Autoweek race reports and from some entry lists. Thanks to David McKinney and Wolfgang Klopfer for providing these. Identifying the classes and model of some entries has proved very difficult so all new information would be welcomed.

1969-1971 US information has been collated by Chris Townsend using Autoweek reports. All comments, clarifications, corrections and additions are most welcome.

1972-1976 US information was originally collated by Wolfgang Klopfer, converted to database format by Dawn Harrison and checked by Jim Thurman and Don Capps. Wolfgang's main sources are Autoweek and individual SCCA results bulletins but Autosport, Autocourse and Road Racing Annual have also been consulted.

US SCCA Runoffs, Nationals and Regionals results were collated by Wolfgang Klopfer from Autoweek reports. These reports were usually very brief so the information on the majority of races is limited just to the identity of the FA class winner.

Some race programs have also been used for entry lists and other information. My thanks to Richard Coe for the generous contributions from his collection.

All comments, clarifications, corrections and additions are most welcome. Please email Allen if you can add anything.
