Too bad the engine is not the original Offenhauser motor, instead has a Chevy smallblock engine. Guess it would be more reliable if you want to race the car still. from the article: Mike Devin Bought chassis 7224 and 7228 from Dan Gurney in 1972. Lloyd Ruby raced the cars in 1973 and 74, first as Commander Motor Homes and then as Unlimited Racing with Bill Finley as the crew chief. Vatis Enterprises bought both the cars and had Johnny Parsons and Steve Krisiloff race them, also with Bill Finley as the crew chief. .
