Can a 180 pump be replaced with a 215? The reason I asked is that someone told me there was a difference in the engine setup also?

 

As far as I know the only differences in the motors that originally came with the 180hp and the 215hp pumps would be injectors and piston ring height. Theres no problem at all installing a 215hp pump on that truck. The guts of the pump are obviously different. Probably mostly in the lift of the cam.

 

the camshafts in the engine are different to aren't they?

 

Never read anything about that, hopefully someone posts to add some info.
I wish someone had an online fiche for these motors =(
