The Cheetah was built by Bill Thomas to compete with the AC Cobras. It was light and very fast but didn't handle that well. Bill Thomas had a race car fabrication shop in CA. and did a lot of secret projects for Chevy. He was building a wild 63 Nova for Chevy with a fiberglass fastback body but Chevy canceled the program with another one of their racing bans in 1963 that axed the Corvette lightweight Grand Sport and 427 Mystery Motor. There were three of the fastback Novas built. Bill Thomas joined up with Dick Harrell and Nickey Chevrolet and built some of the first 1967 427 Camaros and Chevelles.
