Just remember that you're going to need to have the crank polished, get new main and rod bearings, new piston rings, block honed or bored(maybe, hopefully not) engine gaskets, new push rods(I wouldn't use used ones) machine work on crank, balance crank/rods/pistons(with rings) if you tackle this let me know, I'd like to join on the build. I'm also curious how much difference it makes. I've been really curious about the 4.7 strokers, but don't want to overbore until time for rebuild.
The difference between stupidity and ignorance. Ignorance is doing something wrong and not knowing better. Stupidity is knowing better, but doing it anyway. Don't be stupid!
