The GT500 was basically a factory-authorized tuner Mustang created by Carroll Shelby. Introduced in 1967, the GT500 joined the GT350 on showroom floors and offered a 428-cubic-inch Police Interceptor engine with a conservatively rated 355 horsepower. Despite the larger engine, it was actually designed to be a more usable road-going vehicle than the lighter, race-ready GT350. Because of this, and its negligible premium over the GT350, the GT500 was an instant hit, just as it remains to this day.
