Notes on the cars:

  1. Lola T140 [SL140/8] (Jerry Hansen): New to Jerry Hansen for the 1968 US series, then to John Mahler (Bettendorf, IA) for the 1969 series. Subsequent history unknown but believed to be the car acquired by Wayne "Bing" Sherer (Buffalo, NY) in 1972 and raced in SCCA Nationals. To Phil "Butch" Hollenbeck for 1973, then to Art Cross (Auburn, NY) who ran it in to Florida for several years. Via Owen Starr, Lou Pavesi and Rick McLean to Mark Rincon (Redding, CA) and Hal Williams by 1994, for historic racing. Later sold to Richard Cross, then via Rincon to John Bryant (Adelaide, Australia) at the Monterey Historics in August 2007 and imported into Australia. Crashed at Philip Island March 2008, but rebuilt and raced in the 2011/12 Tasman Revival series. More information about Lola T140 SL140/8
  2. Brabham BT21A (Joe Alves): Joe Alves (Sherman Oaks, CA) raced a #66 Brabham from the start of 1968 to mid-1969, finishing fourth in SoPac FB in 1968 and fifth in 1969 and it is assumed that he had the same car throughout. It was identified as a BT21A by Bob Schilling in his report on the Riverside Regionals in early 1968 (Post Grid Vol 6 No 2). This is likely to be the car previously driven in the same SCCA Region by Dave Webster.
  3. McLaren M4B [200-27B] (Chuck Dietrich): For Chuck Dietrich (Sandusky, OH) in Formula B in 1968, replacing the similar 200-10B that he had raced in 1967. Subsequent history unknown until bought from Joe Zuniga (St. Paul, Minnesota) by James Harayda (Bloomington, Minnesota) in April 1978 as a FB car. Harayda raced it in FB in 1978 then converted it to FC for 1979. Traded to Scott Livingston (St Louis, MO) in 1980 then on to Jon Rhodes (Webster Grove, MO) 1981 who converted it to CSR with an Alfa engine and qualified for the Run-Offs in 1982. Sold to Scott Holman (Frederick, MD) July 1983 and continued in CSR until 1989 when sold to Henry Alexander and Wes McNay. Rebuilt with a new Marc Bahner tub which was modelled on Jim Brown's 1967 monocoque. Restored to Formula B specification and sold to Harry Mathews (Arvada, CO) March 1996 for his Mathews Collection of McLarens. Sold to Shigeru Motohashi (Japan) 2004 and raced in the Japanese Interclub Historic Car event at Tsukuba in 2009.
  4. Brabham BT6 (Charlie Adams): Charlie Adams (Manhattan Beach, CA) campaigned a Brabham Formula B car from late 1965 through to early 1968 when he replaced it with a new BT21C and it is assumed that he ran the same car throughout that period. A report on the May 1968 CDR Pro race in Finish Line identified it as a Brabham BT6 and Adams described it as a 1963 Brabham when he advertised it in CP&A in April 1968.
  5. Cooper Mk IV 'T51' [F2-14-60] (Walt Mathewson): Delivered to F Armbruster (USA) according to the Cooper Register.
  6. Brabham BT15 (Ted A. Clark): Ted Clark (DeKalb, IL) raced a Brabham BT15 in Formula B in 1968, equipped with a Cosworth Mk 13 engine and running as #56 and typically entered by Team Nappi of Rockford, Illinois. Clark advertised the car in April 1969, saying that it had a Hewland 5-speed gearbox and 7" and 9" wheels. Nothing more known.
  7. Brabham BT21B (Fred Opert): Fred Opert, the leading US racing car importer in the late 1960s, raced a Brabham in Formula C in 1968. At the end of the season, he advertised it in CP&A (7 Dec 1968) as a BT21B with fuel-injected SCC engine, six-speed Hewland gearbox and "extra light chassis and body". Opert's car was sometimes reported at races as a Formula B and it's unclear whether this was a mistake or whether Opert was driving other cars he had in stock. Sold to Dewey Harless (Portland, OR) for 1969 and raced with great success in FC. Harless advertised it in July 1970, still with its fuel-injected SCC engine but as a BT21, not a BT21B. He retained it until early 1971 when it was sold to Butch Owsley (Aptos, CA/San Jose, CA) who ran it at Laguna Seca in June 1971. Subsequent history unknown.
  8. Brabham BT16 (Carson Baird): Carson Baird (Birmingham, AL or Beltsville, MD) drove a Brabham in Formula B in 1968, racing in three Pro events and also scoring 15 pts in NEDiv Nationals. His car was identified at Mosport Park 25 Aug 1968 as a BT18 but when he traded the car to Fred Opert for a new Chevron, Opert described it as a 1965 F2/FB, indicating a BT16. He entered a Chevron for the Run-Offs but did not start and evidently gave up on the car as he was in a Brabham again at the start of the 1969 season. He upgraded to a Winkelmann WDB2 mid-season. Nothing more is known about the Brabham.
  9. Lotus 27 (Tom Tufts): A Lotus 27 bought new by Cliff Phillips (Palos Park, IL) and raced in Formula Junior and then fitted with a Ford twin cam to run in Formula B in 1965. Subsequently sold to Ike Uihlein and driven for him by Dick Eisenmann. Then sold to Tom Tufts (Milwaukee, WI) and raced by him in Formula B in 1968 until damaged in an accident. The damaged car is believed to have been traded to Fred Opert later in 1968.
  10. Brabham BT21A (Bill Simpson): During a trip England over the 1967-68 close season, Bill Simpson (Los Angeles, CA) bought a new Brabham to replace his FB-spec Lotus 51. It was described as a Brabham BT21A but if it was new in January/February 1968 then it is more likely to have been a BT21C. He raced the car in west coast SCCA and FRA events during 1968, usually as #58.
  11. Cooper T76 (Tom Wingett): Tom Wingett (Cheyenne, WY) advertised his Cooper T76 Formula C car in CP&A 27 Jan 1968 noting that it had F1 suspension and a dry sump BMC engine.
  12. Brabham BT21 (Mike Hiss): To Mike Hiss (Laurel, MD) to replace the earlier Brabham that he "demolished" in practice for the Bridgehampton National in July 1967. He raced the BT21A for the last two Pro races, finished third at Lake Tahoe. Retained for 1968, finishing third at Palm Beach in February and then winning at Marlboro in March. Second in Bridgehampton National and won a Regional at Marlboro but less successful in the Pro series. Last seen when crashed at Lime Rock in September 1968 following a suspension failure. Hiss had by that time moved up to Formula A with a Lola T140 and it is not known whether the Brabham was rebuilt.
  13. LeGrand Mk 7 (Don Richardson): Don Richardson (New Orleans, LA) US 1968 (first seen as DNS at R1 Continental Divide 26 May 1968; only known race winning a SCCA National at Galveston Airport 7 July 1968; also on entry list at R8 Laguna Seca 12 October 1968). Advertised 14 Dec 1968 as "1250 lbs of rotting hell", complete with a Chevy running on Webers and Hewland LG500 . There is no sign of the car in 1969 but Richardson advertised it again on 6 Jun 1970. Sold to Art Eatman (Austin, TX) and raced in the SCCA SW Division in 1971, winning the FA class. DNS at Road Race of Champions Road Atlanta 27 Nov 1971. Art sold the car to Karl Patton (Austin, TX) who planned to add a wing to the nose and use it for autocross. Almost certainly this car advertised by John Anderson (Austin, TX) 5 May 1973. The engine details mention in the advert ('Crane heads, Isky roller') matches that of Art Eatman when he advertised the Richardson car from the same city a year before and is also very similar to the advert by L Nelson Spohnheimer (Plano, TX) in Dec 1973. Walt Taylor recalls all four Texan owners and rates it 'overwhelmingly likely' that they had the same car. He recalls that Anderson used the car just in Autocross or testing. Subsequent history unknown.
  14. Brabham BT21A [4] (Dick Smothers): Sold new to Lou Sell (Fullerton, CA) and first seen in the Pro Formula B race at War Bonnet in late June where Sell qualified on pole and finished second. Then raced in SCCA Regionals and occasional Nationals in California, and in the pro races at Mont-Tremblant and Lake Tahoe at the end of the season. Sold to Sell's backer Dick Smothers (Woodland Hills, CA) for 1968, although Sell also raced it in one SoPac National early that year. To Fred Opert late 1968 in part-exchange for a new Chevron and from him on to Ken Duclos (Boxboro, MA) for 1969. Duclos believes he returned it to Opert at the end of 1969 when he acquired his new BT29 and it next turns up in 1971 with John Sorbello (Lafayette, MA) who widened the cockpit section into a two-seater and added a Chevron B16 body. However, it is possible that the dates of this are wrong and that Bob Isnor (Newton, MA) raced it as a FB before it went to Sorbello. Later to John Kauffman who thought he had bought a Chevron and then to Joe Maria (White Plains, NY) in the early 1990s. It was restored by David Irwin to BT21A spec and was still with Maria in 2007. To Bob Lima (Meadowbrook, PA) by October 2009 and later repainted in Sell's colours.
  15. Brabham BT15 (Oliver Grant): Oliver Grant (Norfolk, VA/Wheaton, MD) raced a Brabham in Formula B in late 1967 and the first half of 1968. A Revs Institute photograph shows that it had a 1966 bodywork section but short rear uprights, implying that it was a 1966 Brabham BT15. Nothing more known.
  16. Brabham BT21 (Fred Ashplant): Raced by Fred Ashplant (Franklin Lakes, NJ) and first seen at Lime Rock in early July where Racing Magazine called it "his new Brabham FB". Won the SCCA National at Bridgehampton two weeks later and the Pro race at Mont-Tremblant in September. Finished third in the NEDiv FB title. Retained for 1968 but used much less that season. In 1969, Ashplant ordered a Brabham BT29 and sold the BT21A to Pete LoBianco (York, PA). However, the BT21A was in Fred Opert's stock during the summer of 1969 and as the car had last been raced as #47, it seems likely that this was the #47 FB Brabham that Opert raced a couple of times before his BT29 arrived.


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.

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.
