GM ultimately decided to postpone the release of their fifth-gen Corvette, largely due to budgetary constraints. However, the development of a new powerplant for the aging C4 Corvette was greenlighted nonetheless. This engine carried the LT1 designation, and prove quite capable. The 1992 LT1 would serve as a bridge between GM small-block development.

During many production years, consumers were provided with multiple engine options to choose from. This was especially true during the late 1960s. However, by the late 1970s, GM had begun to significantly scale back the number of production engines offered for the Corvette. This trend peaked in 1981, when only one engine, known as the L81, was offered to buyers.

Finally, in 1973, consumers were left with only three available engine options, two of which were of a small-blocks. The third was the 454 cubic-inch LS4, would only survive for two years, serving as the final big-block to grace the Corvette’s engine bay. By 1975, the Corvette was only offered with one of two engines, of which, the 350 cubic-inch L82 was the most formidable.

Was the 454 cubic-inch LS4 one of General Motors’ most powerful big-blocks? Absolutely not. However, it is historically significant nonetheless. The LS4 served as the end of the road for the big-block Corvette, as America’s sports car returned to its small-block roots. Today, many collectors seek out LS4 equipped Corvettes.

The 350ci V8 was actually a further extension of GM’s decade-old small-block engine series. In a bid to further cement the Corvette’s performance legacy, subsequent modifications to these earlier engines were made, thereby giving birth to one illustrious platform. It would serve as a mainstay of the Corvette line for over three decades to come.

1967 – L88 (427CI) Engine Guide: Specs, Features, & More

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.

2014 LT1 Engine Guide: Specs, Features, & More

It seems as if many of the engine-related advancements found in standard General Motors’ vehicles, first came to prominence when implemented in Corvette production, a decade or more prior. One such engine, which could easily be considered revolutionary, is the 2014 6.2-liter LT1. This fearsome powerplant was as sophisticated as it was powerful.

1966 – 7.0L (427CI) V8 Engine Guide: Specs, Features, & More

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.

In the midst of the Z06’s development, engineers knew that something truly remarkable would be needed to best the base Corvette’s 400 horsepower LS2. In its production form, this new small-block V8 came to be known as the LS7. The LS7 was nothing short of all-powerful, featuring a displacement of 427 cubic inches and an output of 505 horsepower.

For more than a decade after the Corvette's initial release it had small-block power. In fact, the 265 cubic-inch V8’s 1955 introduction was largely responsible for the Corvette’s validation as a sporty, performance-minded vehicle. However, by the mid-1960s, those behind the scenes at Chevrolet had begun developing a new powerplant. This engine would become the first big-block V8 to be used in Corvette production.

Though the 283 cubic-inch V8 seldom receives its share of attention in a world dominated by LS and LT series engines, this early Chevrolet small-block was ahead of its time. The 283ci showcased a plethora of new and innovative tech, and highlighted the engineering prowess of legendary Corvette luminary, Zora-Arkus Duntov.
