Choosing between the two engines

You can also reference the original window sticker or the vehicle’s RPO codes to verify the engine option. In addition, the engine choice often correlates with the model trim and whether the truck was configured for work use or as a more equipped version.
Identification tips and quick checks
Common quick checks include visually inspecting the engine bay for the engine size markings, consulting the VIN and build sheet when available, and reviewing any maintenance receipts or owner manuals that accompanied the vehicle from the factory.
