Founded in 1938 by Vic Edelbrock Sr., the company was borne out of his desire to increase the performance of his very own 1932 Ford Roadster, designing a new intake manifold that would soon catch the attention of his friends and fellow drivers. From his humble garage, Edelbrock Sr. would soon become one of the most sought-after performance replacement automotive manufacturers in history. With his legacy carried on by his son Vic Jr. and a trusty team of talented mechanics and engineers, Edelbrock soon developed parts for racing that were commercially unavailable due to the sanctions imposed during the war.
