The late Harry Morrow, founder of the historic Autobooks in Burbank, got Bob interested in building and racing 500cc Formula III cars and began racing them as well. That's Bob at Santa Barbara Airport road course in 1952: You can't take the hot rod out of a hot rodder. Bob built the first 500cc (chain driven) Formula III car in the U.S., his "Ariel Special," using a Fiat Topolino chassis and the engine out of his Ariel Red Hunter motorcycle. "I made a piston for it that was 15 to1 compression, we ran straight methanol with a little castor oil." Bob's engine produced 40 horses (stock was 17).
