A crate engine is the first step and the fundamental achievement for all car enthusiasts who want to build or assemble the car of their dreams: in fact, this engine is built in the factory and directly delivered to your home. The block is fully assembled and includes crank, connecting rods, pistons, valves, and often a carburetor.

Many of these engines produced by General Motors and Chevrolet also come with a warranty for fairly high mileage (about 50 thousand miles) or a period of 2 years and ensure incredible performance.
