1966 Ford Mustang

1966 Ford Mustang Fastback K-Code â?" GT350 Tribute with 289 V8 and 4-Speed Manual Why This Car Is Special The 1966 Ford Mustang Fastback is one of the most recognizable shapes in American automotive history, and the K-Code variant sits at the top of the production-engine food chain for that model year. The 'K' designation in the VIN identifies this car as a factory High Performance 289 car â?" the 271-horsepower solid-lifter version of Ford's small-block V8 that required a higher compression ratio, a stronger bottom end, and a more aggressive camshaft than the standard 289 offerings. Ford built K-Code Mustangs in relatively small numbers compared to total Mustang production, and the fastback body style â?" referred to internally by Ford as the '2+2' â?" makes this combination more sought after than a K-Code coupe or convertible.
