I have a 2004 engine and am about to purchase a 06 or 07 engine. Should i stick the whole 07 in or are there parts that i should take off the 04 to put in the 07. Anything better for big HP numbers on the 04??

I would say use the newer motor..... better hpo system from what I've heard..... that's the only real big diffrence that would hold you back at this point

Pretty sure the 05+ HPO system is better. Didn't Shawn put an 05 system in his 04?

I think you're right on Shawns truck but I've always read where the 03-04 had the better hpops, it even says on Elites site under the 225 injectors "If you have an 05+ model year then please see our HPOP upgrade kits to maximize the potential of this injector or choose a 205cc injector."

Hmmm, why is dieselsite working on making a 03/04 pump and not an 05 pump? I would think if the 05 was worse the would be working on that one...

03-04 pumps are easier to mod. they are piston style pumps and are pretty much the same as the 7.3 in design. the 05+ is a cam style. i prefer the cam style for anything reving over 4k. piston pumps like to come apart in high rpms

According to diesel site a stock 05+ HPOP can actually put out a higher volume than a stock 03-04 HPOP it is just that the 05+ delivery system is the limiting component for the pump as that is why they make an upgraded delivery system to utilize the full potential of the stock pump. They are also working on a HO HPOP for the 05+ but havent released it yet. Hope this helps.
