From xtremediesel.com:

Attention 2004 Model Year Owners. to ensure that you have an early 2004 Dodge Cummins 5.9L Diesel you must check the engine tag (A Red or Silver Tag) located on the drivers side of your engine. The tag should show a horsepower rating of 315. If it does not you most likely have a 2004.5 Dodge Cummins 5.9L Diesel.

Attention 2004 Model Year Owners, to ensure that you have a 2004.5 Dodge Cummins "600" 5.9L Diesel you must check the engine tag (A Red or Silver Tag) located on the drivers side of your engine. The tag should show a torque rating of 600. If it does not you most likely have a 2004 Dodge Cummins 5.9L Diesel.

you should be able to tell by the settings sticker on the side of the valve cover too.

sounds like a 04.5 to me. my early o4 is 305hp. that is the HO motor.

Changeover for the 305 to 325HP was Christmas vacation in December 2003. If its an 04 model built from July 03 to December 03 its a 305/555. If its an 04 built from Jan 04 to July 04 then its an 04.5 325/600

Which VIN # constitutes the H.O. motor, the 6 or the C? I'm looking to pick up an '04 and its 8th # is a 6.
