1955 was a break out year for Chevrolet.  It's new small block V8 designed by engineer Ed Cole, who'd later become the President of GM, was going to set records.

Production of the original small-block began in the fall of 1954 for the 1955 model year with a displacement of 265 cu in (4.3 L), growing incrementally over time to 400 cu in (6.6 L) in 1970. Several intermediate displacements appeared over the years, such as the 283 cu in (4.6 L) that was available with mechanical fuel injection, the 327 cu in (5.4 L), as well as the numerous 350 cu in (5.7 L) versions. Introduced as a performance engine in 1967, the 350 went on to be employed in both high- and low-output variants across the entire Chevrolet product line.

Although all of Chevrolet's siblings of the period (Buick, Cadillac, Oldsmobile, Pontiac and Holden) designed their own V8s, it was the Chevrolet 350 cu in (5.7 L) small-block that became the GM corporate standard. Over the years, every American General Motors division except Saturn used it and its descendants in their vehicles.

Finally superseded by GM's Generation II LT and Generation III LS V8s in the 1990s and discontinued in 2003, the engine is still made by a GM subsidiary in Mexico as a crate engine for replacement and hot rodding purposes. In all, over 100,000,000 small-blocks (as of November 29, 2011) have been built in carbureted and fuel injected forms since 1955. In many respects, the later Generation II and Generation III engines still in production today for various vehicles still trace some of their design lineage to the "small block" design concept first laid down by Ed Cole and his team.

The small-block family line was honored as one of the 10 Best Engines of the 20th Century by automotive magazine Ward's AutoWorld
