Auction Block: 1968 Shelby Mustang GT500 KR

When it first rolled off the production floor, the Shelby Mustang GT500 changed the automotive world forever. But by the late ’60s, the competition was starting to catch up. Shelby had an answer, however, which can be found under the hood of this 1968 Ford Shelby GT500 KR pony car that’s headed to auction.

The standard GT500 was rated at 335 horsepower — not a small figure, especially at that time. But its follow-up you see before you got boosted to “at least” 400 horsepower alongside a whopping 440 ft-lbs of torque, making the GT500 KR a monster by comparison. And the horsepower rating wasn’t all that got tweaked, either. This KR also boasts staggered rear shocks for better stability, low-riser heads borrowed from the 427 engine, a beefed-up crankshaft, larger power disc brakes, power steering, and more. Best of all, it can be yours — so long as you shell out the expected $170,000+ price tag.

Purchase: $170,000+
