Thunderbolt
As the muscle car market took shape, Ford introduced a Fairlane for drag strip racing for 1964, heavily modified to incorporate a 427 CID (7.0 L) V8 with two four-barrel carburetors on a high-riser manifold, ram-air through the openings left by deleting the inboard headlights, equal-length headers, trunk-mounted battery, fiberglass hood, doors, fenders and front bumper, acrylic glass windows, and other lightweight options including deleted rear door window winders, carpeting, radio, sealant, sun visors, armrests, jack, lug wrench, heater, soundproofing, and passenger side windshield wiper. This special model, of which 111 to 127 total were made depending on who you ask, delivered 500 hp (373 kW) at 7,000 rpm and was known as the Thunderbolt.
Racing in NHRA Super Stock class on 7-inch (180 mm) tires, the Thunderbolt was based on the mid-level Fairlane 500 two door pillared sedan, and set elapsed time and top speed records in 1964 at 11.6 seconds and 124 mph (200 km/h), took the Super Stock title, and won the Manufacturer's Cup; it is very possibly the fastest drag racing production car ever produced. The car as delivered was in fact slightly too light to meet the NHRA 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 then required a metal front bumper, so the cars began to be supplied with an aluminum bumper and previous purchasers were supplied with one.
Finally the NHRA changed the rules to require 500 models of a car to be manufactured for Super Stock competition, and Ford, which had been losing $1500 to $2000 on each Thunderbolt sold at the sticker price of $3900, gave up. The first 11 Thunderbolts were painted maroon, which was known as Vintage Burgundy in Ford literature, the rest were white; 99 had manual transmissions. Many still race, still delivering quarter mile elapsed times in the very impressive 11 second range and occasionally lower. About 50 similar Mercury Comet Cyclones were also produced by Ford in 1964, destined to be modified to represent Ford in A/FX competition, which they dominated as well.
