So I hope i posted this in the correct spot. I have a 1994 3.0 that's freshly rebuilt with a freshly rebuilt 5 speed behind it. I was curious how hard it would be to swap the 3.0 into a shell that had a 4.0 in it. A tree jumped out and hit the front of my truck, I don't want the fresh rebuilt motor and transmission to go to waste so I found a donor but it had the 4.0 in it. So how hard would that be?
