Engines
BluePrint Engines builds Chevy and GM crate engines. These crate engines are high-performance drop-in engines offering substantially more horsepower than the factory original. Crate engines or crate motors from BluePrint Engines offer a custom builder, hot rodder, or kit car builder an engine that is ready to drop in the vehicle. BluePrint crate engines come complete with all the components that will be needed to start and run the engine very quickly. No extensive cleaning or installation of parts is required. In addition crate engines are dyno-tested and are shipped with a documentation of their high-performance power curve. Forged cranks and pistons are also available on all models. This page outlines Chevrolet and GM LS engines. We also offer Ford crate engines and Chrysler crate engines.
