By the 1960s the Corvette was beginning to hit its stride, especially in terms of performance. While the GM small-block reigned supreme initially, the 1960s would see the rise of the high-displacement big-block, complete with 400-plus horsepower. This was on par with the times, as the horsepower wars of the muscle car era were in full swing. This resulted in several extremely memorable power plants.
No list of formidable Corvette engines would be complete without including the 1967 L88. The L88 was a fire-breathing variant of GM’s 427 cubic-inch big-block lineup, which served as nothing short of a production race engine. Officially rated at 430 HP, the L88 was capable of propelling its C2 host to previously unattainable performance status. The L88 was nothing, if not a loosely veiled production race engine.
Upon its 1953 release, America’s sports car mustered only 150 HP, yet in 1966, the newly evolved Corvette nearly tripled this level of output. It was in 1966 that the Corvette was offered with not one, but two different variants of the robust 427 cubic-inch (7.0L) V8. In its most potent form (L72), the 427 officially produced 425 HP. However, most believe this value to be grossly understated.
