Roush, Edelbrock, Chevrolet and More

Roush Engines

Combining engineering with racing, Roush founded Roush Performance Engineering in 1976 and began selling high-performance engine designs to the world of motorsports. His racing team's ability to win and a brilliant solution-oriented approach to building engines earned Roush a reputation associated with excellence.

Edelbrock Engines

Edelbrock engines are known for research and development, manufacturing, and state-of-the-art testing facilities. Racing enthusiasts have called the Edelbrock manufacturing approach "the most state-of-the-art" in the United States. Founder Vic Edelbrock Sr. bought his first project car, a 1932 Ford Roadster, and designed a specialty engine and intake manifold that instantly became a sensation in the world of "hot rods" and racing.

Chevrolet Engines

Chevrolet Performance began engineering high-performance crate engines 50 years ago and today continues to manufacture new horsepower focused engine designs with a distinctly American sound. Chevrolet offers full crate engine drop-in kits to help high-performance car drivers get back to leading the pack fast.
