The Fairlane Thunderbolt was a limited edition high performance variant of the Fourth Generation Ford Fairlane only available for the 1964 model year. The Thunderbolt was a factory experimental drag racing car that received a number of modifications most notably the use of Ford's 7.0L (427 cu in) 'FE' V8 engine. This engine featured dual 4-barrel carburetors, and while officially rated at 425hp, this unit is believed to have produced closer to 600hp. A total of 100 Thunderbolts were built, with 51 automatic versions, and 49 manual examples.
