So just clean it up and a couple of new pistons and it'd be ok or is there something deeper? If its just pistons just pick up some 4.8 flat tops; I've been dying to see someone try this.
Sucks about the problems man.

From what I understand (and makes sense) If both the 4.8 and 5.3 have the same bore (truth) then the stroke is different. Meaning either, the 4.8 has shorter rods, or the piston pin is at different heights. If you use the 4.8 pistons, they will protrude the top of the block at the top of the stroke.

TurboGibbs on here I think said that the pin heights were the same. The 4.8 has longer rods and a shorter crank. Here's an interesting thread on it:
