What are Chevrolet crate motors?

Named as such because they come in a crate, rather than as part of a car, crate motors are stand-alone engines that customers purchase for projects, or as replacements for existing motors. Chevrolet manufactures and sells around 50 different varieties of crate engine.

Chevrolet's crate engines range from the four-cylinder, turbocharged LTG, which makes 272 horsepower and 295 foot-pounds of torque, to the eight-cylinder, 7.4-liter LSX454R, which makes 770 horsepower and 612 foot-pounds of torque. Chevrolet's crate engines come in various forms of completion to suit customers' needs. The LSX454R, for example, comes without a turbo or supercharger, but can easily accept one if the owner so desires.
