Need your engine serial number, that engine most likely has aluminum pistons, can not go to high with the hp. If you overhual, you could upgrade piston packs, cooling jets, camshaft and injectors to make it a 550hp

I had the motor rebuilt 200000 mi ago and looking at the reciept the part# for the cyl packs are or8333.the new pistons were 2 piece pistons becouse the motor had a recall on the alum pistons getting holes in them.when i had it rebuilt the mech told me that they put 410HP parts in and they were better? i will say it dose pull better since rebuilt then before.im going down to the truck now to get the ser# check back later.Thanks Walt

on the emissons sticker at the back of the valve cover.....it looks like it says 5ek48751....but its hard to read
the sticker on the front end of the valve cover is torn due to a pressure washer
if my wifes home ill have her see if its right (i have a new data plate at home, just havent scribed the info on it -
My dad had the 5ek 455hp but when the overhauled it he had them build it a 550hp....What a difference that made.
Oh and when it was at 455hp, the fuelmileage sucked big time! It ws the gutless wonder that sucked fuel.....
