We figured were gonna have to take .150 to clear. I sure hope cause Im having a hard time finding a machinist who wants to do it. They all seem scared to make the cut. I told them all its no big deal, I wish I had a lathe good enough cause I would do it myself but the one I have access to is way to outa spec and would sing like a canary if I chucked it up.
When I built my 451 many years ago I just lightly beveled the 440 crank and took my 4" angle grinder to the inside of the block. It didn't take much work at all but the shop that balanced it did [censored] about it. Lots of drilling. They weren't into the big engines so much.
