What would be the max, safe, overbore to go to on a 1976 360 Mopar, I know its already thirty over, but I want to rebuild the whole thing, would .040, .050, or .060 be getting this too thin. How about a 1964 273, how far could one go on that? I,m not talking hogging them out to gain displacement but the minimum to fit a new set of pistons and completely rebuild the engines. Dont want to buy a block thats going to end up with rubber cylinder walls. This is not a pro motor I'm building but a strong street motor that will push some decent oats.
