Donald Bigbie’s ’69 Sport Coupe

Donald built his ’69 to be more-show-than-go since he did not intend to race it. He instructed his engine builder to make a strong street engine with torque down low. The finished car turned out just as he wanted, it looks great and has plenty of power where he needs it (torque comes on strong early and stays flat). You can get a better look at it on the cover and inside the October 2002 issue of Super Chevy as well as inside the next issue of CAMARO PERFORMERS.
