GM Performance Parts Information

Chevy Crate Engines - GM Performance sets the standard for performance products made for Chevy vehicles. They are at the forefront of new engine development. When you have that kind of backing, you're bound to see some performance crate engines that build monster power. GM Performance offers several Small Block 350 Chevy crate engines, LS crate engines and Big Block Chevy crate motors to match every enthusiast's need for speed. The 350 crate engine is one of our best sellers. They also guarantee their engines with an incredible warranty. You can be sure that you're getting a crate engine that is built right and will last.

There are many options with GM Performance motors. Many 350 crate engines and 454 based engines are available assembled with your choice of a turn-key engine or an almost ready to run configuration. You can even buy a kit and assemble the engine yourself, saving a few bucks in the process. If you want a good short block, GM Performance can help you there too. A lot of the short blocks that make up complete engines are available separately. You can start with a good core short block and custom build the top end to your specifications. The range in engines is also evident in the level of performance you would like. Many small block Chevy engines are available to get you where you need to go. Start with a 350 crate engine for that everyday runner. For a little more power try a 383 stroker crate engine. Step up to the LS engines to add modern power to your classic ride. The technology in the LS series of engines is impressive. They look great in old muscle cars as well as new! If it's raw thumping horsepower you crave, look at the 572 - 720 HP GM Performance crate engine. It gives you monster horsepower with potential to build even more.
