With GM's cancellation of its prohibition against engines larger than 400 cubic inches in the A-Body intermediate models for 1970, Chevrolet enlarged its Mark IV “big-block” to 454 cubic inches and unleashed RPO LS6, the ultimate “bowtie” weapon. Underrated at 450 bhp and 500 lbs-ft of torque, the LS6 delivered 11:25:1 compression, big-valve closed-chamber heads, a 780-cfm Holley four-barrel carburetor, and a radical solid-lifter camshaft, supported by a stout four-bolt-main block with forged internals, backed by either a Muncie M-22 “Rock Crusher” four-speed or hard-shifting M40 Turbo 400 automatic. While the Corvette was originally slated to receive the LS6, that combination was postponed until 1971. Compression was lowered to 9.0:1 and open-chamber heads were used, with all else remaining unchanged. Rated output was down slightly at 425 hp but performance in the relatively lightweight Corvette was massive. With the muscle car era ending, only 188 LS6-powered Corvettes were built in all for 1971.

Already rare, this example is far more so as one of just 20 LS6/four-speed Corvette convertibles produced, with 12 known to exist today. Of those few, this specific LS6-powered Corvette convertible is the only one known to have been factory-equipped with the Muncie M22 heavy-duty, close-ratio transmission and finished in Mille Miglia Red with a red interior. As confirmed by the NCRS Shipping Data Report, this Corvette was shipped new on March 16, 1971 to Chevrolet Engineering at the GM Tech Center (Dealer Code 502 in Zone 0) for testing and evaluation.

The Corvette’s excellent ownership history includes Ronnie and Alvin Steinman and Dr. Paul Noble. As offered, the Corvette clearly continues to benefit from its complete, body-off-frame restoration performed by a well-known and respected NCRS Master Judge. Of particular note, the Corvette's body was found during the restoration process to have remained sound and undamaged. Following completion, the Corvette has garnered an exceptional string of major awards including NCRS Top Flight, Bloomington Gold, and Gold Spinner, culminating in the coveted Triple Crown. In addition to its many show accolades, the Corvette was the subject of a January 2013 Corvette magazine feature article. It retains its all-important original LS6 engine and M22 four-speed transmission and Al Grenning of Classic Car Affirmation Service has authenticated it. A very well known and respected car in the Corvette world, this "1 of 1" example simply ticks all the boxes and marks an exceptional opportunity for Corvette collectors and enthusiasts alike.
