| max overbore on 428 PI? |

I recently got a 428PI motor with a 67 GT500 project car. it's not the original one for the car, but it's got C6ME on it and I was told it is correct for the car. It was rebuilt many years ago, and was bored .030 over according to the pistons having .030 stamped on the tops. I need to tear it down to freshen it up, and there is a deep score in one of the cyliders (how it got there on a rebuilt engine, I have no idea). My question is how far can I bore this block, .040 or .060? Or since it's kind of an important car, should I sleeve the one cylinder?
