I've got an '04 CTD, but am not sure if it's an early or late (after Cummins upgraded the HP and torque ratings) model. Is there a list of VIN's that will identify my truck as an early or late '04?
you can also look on the valve cover. . .if the HP rateing is 325, then you have an 04.5, if it is a 305hp model then you have an early 04. also the build date of the truck will also tell you, after Jan 04 then you have the 600 engine, before that would be the tripple nickel.
