GM Performance Parts

GM Performance engines, transmissions and components have been the ‘Heartbeat’ of hotrods and customs since the first overhead valve small-block v8 was introduced in 1955. Loads of options in horsepower and torque. Complete turnkey options or a solid short block, put the best in your ride today!! You know what you're going to get, proven engineering.

For nearly half a century. Chevrolet Performance has been the go-to resource for enthusiasts of all stripes. From the original Small-Block and Big-Block engines that fueled their start, to the LS and new LT engine, they have never stopped innovating. New and improved products designed to provide the crate-engine, components, vehicle-specific performance parts and accessories you need to build your dream.

Two exciting new crate engines: the ZZ6 360 and the supercharged LT4. The ZZ6 is the latest in their decades-long legacy of building uncompromising Gen I Small-Block performance. It uses LS-style beehive valve springs and other modern features to deliver exceptional high-rpm performance and 405 horsepower. That's more than any 350 Small-Block ever installed in a production Chevy car or truck
