Guess it depends on how worn it is.... Like trav stated his truck has way over 200k miles the bottom end is prolly fine replacing the top end will most likely do the trick. I wouldn't have recommended less than replacing all the worn stuff. If he is going to pull the whole motor might as well swap in a 6.0 80e combo. I am sure his tranny isn't in the best of shape either.
