Ford Mustang Shelby GT500 Convertible

As the new-for-1967 Mustang body shell had been designed from the outset to accept Ford’s larger FE-Series 390 cubic inch big-block engine, Shelby dropped Ford’s higher-displacement Interceptor 428 into the pony car’s engine bay, creating the upscale GT 500, which offered heightened levels of luxury and refinement. While the 428 was conservatively rated at 355 horsepower, actual output was closer to 400 hp with 420 ft-lbs of sheer, tire-scorching torque!

Although this basic powerplant continued to power the GT 500 with modifications through 1970, stylists ensured that the Shelby GTs retained their own unique identities. For 1968, the GT 500 was comprehensively updated with an aggressive new front-end treatment including a lengthened hood line, air scoops and louvered cooling vents, while a neatly integrated rear spoiler was added, as well as revised head and tail lamps, with the rear units being from the 1965 Thunderbird. Inside, a neatly covered roll bar with inertia-reel shoulder belts was added, and for the first time, handsome convertible variants of both the GT 350 and top of the line GT 500 appeared.
