The MK I and MK II models received a GT-40 intake and heads; a 65mm throttle body; ceramic-coated, short-tube headers; 1.6 rockers; underdrive pulleys; and a Centerforce clutch. These items were straight from the Ford Racing Performance Parts (Ford Motorsport) catalog. The GT-40 components helped the small-block deliver a reported 295 hp and mid-13-second quarter-mile times. Snake models featured a stock 5.0 engine with no power upgrades. According to car owner Craig Stockard, his MK I is one of four equipped with a ball-drive Paxton supercharger.
