Long story, but I have a full reciprocating assembly that I acquired from Steve Ferguson, that HE got from another GMCer who received it as part of a warranty settlement from Mondello. The only problem is that (I believe) it has .060 over pistons and rings. I am looking for opinions on whether or not this much of an overbore is an issue on a 455. If it is even questionable, I will try to work out some kind of a deal on those parts and go with about a .030 overbore.
