Buyer's guide
About Chevy engines & transmissions.
Common engine families, transmission compatibility, and what we test before every unit ships.
Chevrolet's small-block V8 and EcoTec 4-cylinder engines are some of the most swap-friendly powerplants ever built. The LS family alone has been in continuous production since 1997, with over a dozen variants sharing the same bellhousing pattern. That makes finding a compatible replacement easier than almost any other brand.
