Crate Engine - Connect and Drive - Turnkey

Crate Engines

Crate: Engine Only Option - Comes complete with intake assembly - injectors - coils - water pump - balancer and flexplate. If looking for a little more performance out of a crate engine then we offer supercharger, Tunnel Ram Intakes, or 8-Stack Systems to enhance a crate engine. With a crate engine, you can start from scratch and build up your own dream engine setup.
