Is there a way to tell real easy on an 04 if its a 305 or 325hp? Like does one have "Caution Fan" on the Shroud and the other not?

 

There's a sticker on the driver's side of the valve cover (or maybe cylinder head, I can't remember which) that has the horsepower rating printed on it.

 

There is a sticker on the drivers side valve cover showing hp. You could also look under the truck and if it has 4" exhaust and a cat it is the 325 hp, unless the exhaust has been changed or modified.The 305 has 3 1/2" and no cat. Hope this helps.

 

Thanks for the help, Its a 305

 

305 = No Kitty
325 = Kitty present from factory
