360 block cylinder wall thickness

Your machinist SHOULD know if it's safe to go. I heard a million people say you can't take a 360 to 4.060. I had mine sonic checked. Thoroughly. My guy said I coulda gone 80 over if needed. 1973 block.

The first really great machinist I've ever seen. He fixed all the crap and left me with a gem. I can't stress how important it is to find a real good guy.

Ah forgot you want the actual numbers. I can't tell ya cause its beyond me. When you look at your sonic sheet there's 64.....I think, numbers....all different places in each cyljnder. Thrust surface this, non thrust that. I don't need to understand it all when he said "it'll survive a pounding".
