By 1975, the Corvette was only offered with one of two engines, of which, the 350 cubic-inch L82 was the most formidable.

The Vette’s performance dropped significantly during the early to mid-1970s, at the hands of newly implemented federal emissions standards, yet it remained relevant. At a point in which many iconic American performance cars fell by the wayside, the Corvette soldiered on.

When the C5 Corvette was finally unveiled critics were quick to notice a thundering new powerplant. It carried the LS1 designation, serving as the C5 Corvette’s base engine for the duration of the production run. Ironically, the C5 Corvette would only ever leave the factory with one of two individual engines. This included the aforementioned 5.7L LS1, as well as the all-powerful 5.7L LS6, which powered the C5 Z06.

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.

The LS1 is the spiritual successor to the “small block V8” that GM uses in rear-wheel-drive cars, trucks, and vans. It was introduced in 1995 as the “GEN III” engine and it only shared rod bearings, lifters, and bore spacing with its predecessors (which was in production 1955 until 2003). Little did GM expect for the LS1 has become a legend.

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.

In under a decade, GM’s small-block received a substantial boost in displacement while also becoming the standard-bearer for several new internal developments in engine technology. These developments ultimately produced a new crop of small-block powerplants based on Chevrolet’s new 327 cubic-inch engine platform. Of the four 327 cubic-inch small blocks available in 1964, none topped the output of the fuel-injected L84 V8.

At the heart of the ZR1 Corvette resides the supercharged 6.2L LT5. GM’s engineering department was also tasked with producing the ZR1’s engine, which would have to perform at a higher level than that of the Z06’s supercharged LT4 small-block. The 755 HP supercharged LT5 would elevate the Corvette’s performance to a level never before achieved.

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.

First, this engine is the most powerful naturally aspirated, internal combustion engine (by a good margin) of any production Chevrolet small-block ever produced. Boasting a massive 670 horsepower, the LT6 trumps almost all its Corvette predecessors (save for the 2019 Corvette ZR1 engine, which boasted 755 horsepower, but needed a supercharger).
