When someone replaces the engine in their registered car or truck, they need to fill out a sworn statement with details about the old and new engine, then send it along with their title to the state and pay a one dollar fee. The state will then send back a new title showing the updated engine. If a rebuilt engine is used, it gets the same number as the old one with 'RC' added in front. If the car's title does not use an engine number to identify the vehicle, the owner does not have to do any of this.
