The L71 was Chevrolet’s most powerful engine in 1967 which replaced the big-block L71 from the previous year. Using it’s famous ‘Tri Power’ intake manifold was rated by the factory at 435 bhp. Costing $437.10, 3,754 Corvettes were made with the L71 options and they could not come with automatic transmissions nor air conditioning.
These Big Block cars would be the high-water mark of Corvette performance and refinement for the C2 series of cars. The 427/400hp L68 came standard from the factory with the Holley triple two-barrel carburetor arrangement called Tri-Power. Only 2101 Corvettes in 1967 received this rare engine option which was a $305.50 cost.
1966 corvette
Despite its popularity, the second-gen Corvette holds the record for the fewest number of production years of any generation Corvette. The most valuable examples of the C2 Corvette live sort of like "bookends" at the start and finish of second-gen production.
At Sebring in 1967, the Corvette L88 made its debut appearance. The L88 package included many competition components which included a M22 transmission, large disc brakes, upgraded suspension and an alumunim head 427. Shortly after the race, the L88 option would be offered on production cars which was a formidable package.
1966 7.0L V8 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.
1967 L88 Engine
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.
