Welcome to the IMSA History unofficial website

This site is aimed at bringing you memories from the glory days of sportscar racing in the US.



"I knew John Bishop from SCCA days and his marketing man was Dick Gilmartin. Dick called me and asked if I would join the new race org. called IMSA. My # 6 licence was the first issued after the Bishop family took the first 5. In 1972 the Baby Grand BFG series started and I was a Toyota dealer and took my wifes Celica and had Ray Heppenstall (Howmet turbine fame) build me a race car. Our first outing was at Daytona where I was on the pole won one sprint race then lost to Amos Johnson's Gremlin. The first IMSA enduro was run at Mid Ohio in 1972 and it was a 6 hour Baby Grand race which I won giving Toyota its first Pro win worldwide. That is it for now. Next car was a 1976 Gremlin then an all new 1978 Toyoya Corolla.

After a few years off to go back to SCCA in FF open wheel racing, I headed back to the now called Radial Challenge Series. Toyota wanted nothing to do with racing so I bought George Alderman's Gremlin which had dominated the series in 1975. Right after my purchase IMSA put a restrictor on the carburetor taking away about 20HP. That was a great year as I finished 4th in the championship that had America's top drivers competing, including. Gene Felton, Nick Craw, Amos Johnson among others. At a race in Ontario Calif. on the starting grid were 11 past SCCA National Champs, unbelievable. The racing that year was WILD. Hemmings story on early RS series. Paul Newman, Rolf Stommelen and me driving for Dick Barbour at Watkins Glen 1979. 1976 Gene Felton and I racing at Daytona and Mid Ohio"
