Edelbrock - Turning Point

Turning Point

Until 1955, Edelbrock made parts only for Ford, Mercury and Lincoln. Few things affected the company (as well as the development of the hot rod market) more than the development of the Chevrolet Small-Block engine (also known as the Gen I) in 1955. Chevrolet delivered three Gen I engines to Edelbrock for experimentation. He used one engine for testing on a dynamometer and another to test multi-carb manifolds for magazine articles. He prepared the third engine for boat builder Henry Lauterback, who immediately set two world records in Miami, Florida.

In 1958, Edelbrock managed an industry first by designing and achieving one horsepower-per-cubic-inch from a 283 cid small-block Chevy with his new Cross Ram Manifold. This breakthrough led him to begin producing manifolds for Pontiac and Chrysler engines.

Another critical turning point in the company's history was the 1964 decision to build a small-block Chevy intake manifold for a 4-barrel carburetor. The C-4B manifold, developed with help from Bob Joehnck, opened the door to a new line of performance products. Although competing with the factory was a risky proposition, it turned out to be a beneficial one, as it allowed the company to expand into a new market.
