It really doesn't matter to me what size I end up with. I can bore it .060 and use what I have with new pistons. I'm not going to thrash it; I'm really just after the original look. So, bore it .060 over and stay with all the stock internal lower end?
Just make sure you have the cylinder sonic tested befor you do anything so later on you won't end up with a pile of junk.
