Hey guys
It's been a while since I posted,hope everyone is doing ok but I had a question:
My truck has 95000 miles and is in perfect working order,does not use any oil and drives well but I'm wanting to put the HO cams in and since I will be putting cams I was thinking about having the heads ported also,basically a top end rebuild.

So the big question is since the truck has 95000 miles on it would I need to rebuild thr bottom end also??? How strong are the bottom ends on the 4.7??
