Recently retired from race driving, Roger Penske teamed with driver/engineer Mark Donohue to build a Camaro (a Z28) into a Trans-Am racecar. The first car was unstable but when Chevrolet pushed a set of stamped 'thin-steel' body panels out the back door, things improved; Mark won at Bryar mid-year. This second Penske/Donohue Camaro, race #6, was acid dipped instead and thus was nicknamed the 'Lightweight', receiving Sunoco sponsorship to boot. It was very successful at both passing tech inspection and on the Trans-Am track itself being reportedly 250 lb underweight. Its greatest success was a 3rd place overall at the 1968 Sebring 12 Hours behind a pair of factory Porsche 907s.
This 1967 Camaro was raced by Mark Donohue for Penske Racing in 1967 and 1968 - winning at Marlboro, MD; Stardust Raceway, Las Vegas, NY; and Kent, Washington. Currently it is powered by a 302 cubic-inch Chevy V-8 engine prepared by Traco Engineering and produces 450 horsepower.Also photographed at :
