‘Corvette Forums’ Marketplace: Numbers-Matching ’72 LT-1 Coupe

The original LT-1 engine is living proof that bigger isn’t always better when it comes to C3 Corvette engines.

For years, talk of high-performance early C3 Corvettes was dominated by big block cars. In more recent years, folks have begun to appreciate the little things — in this case, a seriously impressive small block C3.

The original LT-1 engine was only around for three model years — 1970, 1971, and 1972. It was only offered in Corvettes and Camaros, along with a few Yenko-prepared Novas. Fewer than 5,000 Corvettes were built with the LT-1 slotted in between the fiberglass front fenders.

The LT-1 started off strong in 1970. It debuted with solid lifters, an 11.0:1 compression ratio, and was fed by a 780 CFM Holley four-barrel carburetor. It was rated at 370 horsepower — impressive numbers for a small block, especially in those days.

In 1971, the compression ratio was knocked down to 9.0:1, and power fell as a result. Horsepower was rated at 330; the then-new SAE net horsepower rating was 275. For 1972, it fell further, with a gross rating of 255 horsepower.

Still, it would be the last hurrah for truly high-performance small blocks in Corvettes for over a decade. It was faster, more responsive, and higher-revving than contemporary big blocks. It was also lighter, improving the Corvette’s handling and braking. The LT-1 truly was the best of all worlds back in those days.

Right in Our Backyard

It shouldn’t surprise you that we’ve managed to find one of these rare masterpieces for sale in the Corvette Forums marketplace. This 1972 Coupe is stunning in Steel Cities Gray, and it’s just as pretty under the skin, too. It’s being offered up for sale by longtime member 67 L79 of Atlanta, Georgia.

The numbers-matching drivetrain includes a 3.70:1 rear end and a Muncie four-speed. A previous owner converted to hydraulic lifters to eliminate the need for valve adjustments. According to the ad, the engine was rebuilt less than 1,000 miles ago.

Options include a deluxe black leather interior, power steering, power brakes, and a luggage rack. The paint is around ten years old and still looks terrific from the photos. The seller advises that the car has documentation going all the way back to the original sale.

At $42,500, this car is a bargain compared to many of the big block C3 Corvettes we’ve seen sell recently. For our money, we’d actually rather have the LT-1.
