Chevrolet built only 20 Corvette L88s in 1967, and this one is getting auctioned by Dana Mecum himself, who says it is the only ’67 L88 to retain its original 427-cubic-inch, 430-hp V-8 engine.

The L88 designation referred to a special set of race-ready equipment upgrades to the standard four-speed Corvette that added power and improved handling—first and foremost the engine, which featured 12.5:1 compression, a hi-lift camshaft, 850-cfm four-barrel carburetor, and aluminum heads. A cowl cold-air induction hood was unique to L88s, which were delivered without fan shrouds and chokes and since they were race cars, there was no radio or heater.

It is also the most successful L88 Corvette race car of all time. At the 1970 Daytona 24 Hour Endurance race, Cliff Gottlob’s privateer racing team surprised the field by finishing second in the GT Class and 11th overall. That was one of an astounding number of podium finishes in eight years—nearly 300—including more than 150 outright wins and a streak of 52 consecutive victories, a record at the time.
