A longtime race fan, growing up near Pasadena's speedway, Busby started racing in hot rods. He then went into drag racing but it was sportscars in which he saw most of his success. He raced in Formula 5000 but after an accident sidelined him from that, he returned, initially short-term into sportscars. However he soon became established in the IMSA series, winning four times in the BMW in 1976, and then at Mid-Ohio in 1978. He then raced in the World Sportscar Championship and was a regular at Le Mans. Busby had a brief single-seater spell in the ARS in 1986, before retiring. He became a team manager and oversaw a victory at the 1989 Daytona 24 Hours when John Andretti, Bob Wollek and Derek Bell won. Busby sold his team in 1990 and largely left the sport directly, although he has then competed in historic racing for some time.
