GM Small-Block Enthusiasts

A group for all GM Small Block Enthusiasts.

Chevrolet's V8 is a famous automobile engine. Nicknamed "mouse motor" for its compact dimensions compared to other V8 engines of the time, production began in 1955 with the 265 in (4.3 L) engine used to bring performance credentials to the Corvette. The displacement changed over the years, eventually reaching 400 in (6.6 L), but none caught on like the 350 in (5.7 L) small-block. This engine is still in production today at General Motors Toluca Mexico plant (primarily for the GM over-the-counter Goodwrench powerplants), but is no longer offered in current model year vehicles since the year 2004. Its production numbers were impressive, with more than 90,000,000 built.

From 1955-74, the small-block engine was known as the "Turbo-Fire V8".

Although Buick, Cadillac, Oldsmobile, and Pontiac also designed V8 engines, it was Chevrolet's 350 in small-block that became the GM corporate standard. Over the years, every American General Motors division used the Chevrolet small-block, and its descendents continue as the company's mainstream V8 design today.

The small-block was on the Ward's 10 Best Engines of the 20th Century list.
