Rare 1970 Chevelle SS LS6 Heads to GAA Classic Car Auction in July 2026 - featured image

A 1970 Chevrolet Chevelle SS LS6, one of the most coveted muscle cars of its era, is set to cross the auction block in July 2026, with the sale scheduled for a Saturday run day.

Finished in Tuxedo Black over a black vinyl interior, the two-door coupe presents in a triple-black configuration and comes fully documented. It has been certified by noted muscle car authority Patrick Glenn Nichols, lending weight to its provenance.

At the heart of the car is its matching-numbers 454-cubic-inch LS6 engine, the legendary powerplant that helped define the high-water mark of factory horsepower before tightening emissions and insurance pressures reshaped the American performance landscape. The engine retains a host of correct components, including an 811 water pump, an original-equipment-style dual-line Holley carburetor, an LS6 intake manifold and a 1111437 distributor. The block carries casting number 3963512 with a K129 casting date. A 4-row radiator sits behind the correct core support.

Build documentation traces the car to the Tonawanda, New York, assembly point, with a TO323CRR designation indicating a March 23 build as an LS6 automatic. Backing the engine is a Turbo 400 automatic transmission. The trim and paint codes, 19B and 756, confirm the Tuxedo Black exterior paired with black vinyl.

The Chevelle is equipped much the way an enthusiast of the period would have ordered it. Bucket seats flank a center console, and the dash includes a tachometer with a 6,500-rpm redline. The car also features cowl induction, power steering, power disc brakes, a remote driver’s mirror and an AM/FM radio with an 8-track player. Original-equipment-style dual exhaust completes the package.

With its documented history, matching numbers and the desirable LS6 designation, the coupe is likely to draw strong interest from collectors when it heads to sale.
