Racing in NHRA Super Stock (which required only fifty cars be available to the public), on -wide tires, the Thunderbolt was based on the midlevel Fairlane 500 two-door pillared sedan, and in 1964 set elapsed time and top speed records at 11.6 seconds and 124 mph (200 km/h). took the Super Stock title (with Gas Ronda taking the honors), and won the Manufacturer's Cup. The car as delivered was slightly too light to meet NHRA's 3200-lb (1451-kg) minimum weight unless it was raced with a full tank of gasoline, which would bring it to 3203 lb (1453 kg). NHRA rules at the time required a metal front bumper, so the cars began to be supplied with an aluminum bumper and previous purchasers were supplied with one.
