In 1963 Ridenour campaigned this Genie-Oldsmobile.
 

His best finish in the car was 2nd place at the USRRC event at Pacific Raceways, near Kent Washington, on July 21st, 1963. Pedro Rodriguez won in another Genie, a Joe Huffaker-entered, Chevrolet powered car. Huffaker built the Genies in San Francisco with various engines, from 1100 cc. BMC units to huge Chevy V8s.
