355 hp, 428 cu. in. V-8 engine with dual four-barrel carburetors, Ford Toploader four-speed manual transmission, independent front suspension with unequal-length control arms, coil springs, and anti-roll bar, live rear axle with semi-elliptic leaf springs, and front disc and rear drum hydraulic brakes. Wheelbase: 108 in

Since 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 was able to drop Ford’s higher-displacement Interceptor 428 into the pony car’s engine bay, creating the upscale GT500, which offered heightened levels of luxury and refinement. Although the 428 was conservatively rated at 355 horsepower, actual output was closer to 400 horsepower with 420 foot-pounds of torque!

Although this basic powerplant continued to power the GT500 with modifications through 1970, stylists ensured that the Shelby GTs retained their own unique identities. For 1968, the GT500 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 GT350 and the top-line GT500 appeared.

Delivered new by Ron’s Ford Sales, of Bristol, Tennessee, this 1968 GT500 was, according to the Marti report, originally finished in Highland Green with saddle décor buckets and a white convertible top. Additional options included power disc brakes, power steering, a shoulder harness, a pushbutton AM radio, and the desirable Tilt-Pop steering wheel. At some point, this Shelby was repainted bright red, which still looks great today, as do the top, stainless, and chrome. Air conditioning has been added, as well as an aftermarket radio. The saddle interior still looks quite presentable. The engine compartment is clean and tidy, but it has been upgraded over the years with new hoses, clamps, and modern wear items. Light conservation has been performed to the undercarriage, with a modern exhaust and brackets added. Complete with the Ford and Shelby owner’s manuals, one of the most desirable of all Shelby Mustangs is only a bid away from ownership.
