Edelbrock manufactures performance engine components for domestic vehicles. Camshafts, cylinder heads, intake manifolds, roller lifters, rocker arms, and even full crate engines are just a small portion of what they produce. They even make data acquisition and EFI systems. Edelbrock’s name is one that has been synonymous with performance muscle for decades. With the Edelbrock name winning races since the 1930’s, and continuous development to extract the most power out of V8’s they can, Edelbrock is a brand that will always have a solution for more power.
