"An engine change involves swapping a car engine with another that is not identical, under California law. The state insists that the newly-installed block must be the same age or newer than the one coming out of the car. It must be from the same type of vehicle, such as a passenger car or light duty truck. If the car is California-certified then the engine going in to the car must also be California-certified. Car owners must make sure an engine change does not increase pollution levels, according to California's Air Resources Board. Car owners must submit their car for inspection after an engine change takes place. This is carried out at a state referee station where the vehicle is subject to an emissions test and checked to see that all required equipment is where it should be under California law."
