Walt Cotturone's 1976 Trans Am
(In His own Words)

Mild bracket car at 3500lbs built for longevity. Keeping the faith and running hard at the track since 1980. Aluminum rods in this engine have over 600 passes. Regular maintenance and overhaul to engine and trans\converter\rear axle every 300 passes. Best pass ~1000 feet above sea level 10.14 132. Looking forward to the magic Dave and Marcel can do for the black bird.
