Engine Identification
Engines can be identified by the eighth character of the Vehicle Identification Number (VIN). The VIN number is stamped on a plate located at the base of the steering column on "P" models, and on a plate at the upper left corner of the dash on all other models.
Engine code numbers are located at front of block, at right cylinder head on 5.0L and 5.7L engines and in front of intake manifold on 7.4L engines.
