Ford Mustang Shelby GT500 KR Convertible

The new-for-1967 Mustang’s body shell was designed from the outset to accept Ford’s larger FE-Series 390-cubic inch big-block engine, Shelby dropped Ford’s Interceptor 428 into the pony car’s engine bay and created the GT500, which also offered heightened levels of luxury and refinement.

For 1968, the GT500 was comprehensively updated with an aggressive new front-end treatment including a lengthened hood line, dual air scoops and louvered cooling vents, while a neatly integrated rear spoiler was added, as well as revised head and tail lamps. 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 top-line GT500 appeared.

Although the 360-horsepower, 428-cubic inch GT500 was already very impressive, Shelby unleashed the GT500 KR “King of the Road” with a 428 Cobra Jet engine that was suspiciously rated at only 335 horsepower but in fact pumped out at least 400 horsepower and 440 ft-lbs of tire-melting torque. The Cobra Jet engine included low-riser 427 heads along with a beefier crank, rods and pistons. Additionally, the KR had larger brakes, under-hood suspension bracing and staggered rear shocks to prevent axle wind-up and wheel hop.

This car was auctioned off by RM Auctions in August of 2010 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California and in January of 2012 at the Arizona Biltmore Resort & Spa, Phoenix, Arizona.

335 bhp, 428 cu. in. Cobra Jet V8 engine, C-6 heavy-duty three-speed automatic 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, rear drum hydraulic brakes. Wheelbase: 108".
