302 engine, 11:1 pistons, E303 cam, 351 Cobra Racing heads, Gold series roller rockers, Shelby GT40 intake, multi-port fuel injection, 65mm throttle body, T5 manual transmission, and high torque starter. Engine was built at a Shelby shop in southern California. Car has been driven less than 6000 miles in the last 16 years. Runs great, very strong, and fun to drive. I run the engine every other week and drive it around the neighborhood every 2 or 3 months, otherwise it stays under a car cover.
