The design flair of vintage American automobiles is undeniable.

Chevrolet, ubiquitously referred to as Chevy, is a division of General Motors. It’s 327 cubic inch motor was a small-block V8 engine that enjoyed some popularity through the 1960s, and was an option on two different marques; the Corvette and the Chevelle.; Both were known as "muscle cars" during that era, in part because of the extra kick that this 300-horsepower beast delivered.

The term “small block” is often used to denote an engine of 350 cubic inches or below, which has become the cause of some confusion. In fact, the difference between a small block and a big block is not determined by an ethereal displacement ceiling, but rather by the external physical dimensions of the block itself. Oldsmobile once built a 455 cubic inch small block, and General Motors have produced 400 cubic inch engines on both small and large blocks. The smaller block size was the result of closer bore spacing, which allowed for cheaper production costs and -- more importantly -- a lighter unit that increased the power-to-weight ratio.

History of the Small Block

(REF 2) The small block V8 engine was debuted by Chevrolet in 1955, with a displacement of 265 cubic inches. It has been available in a myriad different forms ever since, with numerous smaller as well as larger displacements offered in response to market forces and technological advances. Increases in maximum bore available progressed as follows: In 1957 the bore was increased to 283, in 1962 to 327, in 1967 to 350 and in 1970 to 400 cubic inches.

The Corvette

(REF 1) Chevrolet introduced the Corvette at the end of June 1953. The original engine was a 235 cubic inch in-line 6, offered in two configurations. It was not until 1962 that a 327 cubic inch V8 became available; of four configurations, one was the 300 horsepower. That year the 300 was the mid-range engine. By 1966 it was the smallest engine, which it remained until 1971. The engine has not been available as a Corvette factory option since the 1972 model year.

The Chevelle

The 1964 Chevelle was offered with a factory 327 cubic inch 300 horse at the very end of the production year. This makes it an extremely uncommon and valuable automobile; only 1,737 were produced. Most cars produced with a 327 through the ’64 model year generated 250 horsepower. Even rarer still, the engine was a factory option in the Malibu SS model Chevelle, a convertible. Before 1968, by which time big blocks had taken over the muscle car market, (REF 4) the engine was one of the most powerful available from any factory.

Mythbusters: The Camaro

(REF 3) Chevrolet introduced the Camaro in 1967 to compete with the massively successful Ford Mustang. One engine configuration offered was a 327-cubic-inch small-block V8; with a two-barrel carb the engine generated 210-horsepower, and with a four-barrel carb 275 horsepower. The second generation Camaro, debuted with the 1970 model year, was offered in an SS -- Super Sport -- version with a 350 cubic inch engine; fed by a four-barrel carb it generated 300 horsepower. The marque was never offered by the factory with a 327 cubic inch, 300 horsepower engine.
