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.
