Of those that have built a 331, did you have to clearance the cylinder skirts, or anything else? Also what is the correct clearance for the crank and rods from the block?
Third question, I knew my current crank had been ground down before, but I recently had it checked and the machine shop confirmed it is a 20/20. I think that means the crank was ground down .020? Does that also mean the mains where .020 as well? If that is the case if I get a 331 kit do I need different bearings than what comes with the kit?
