I've got my 235 torn down and found that it has been bored .060 over at some point in it's lifetime. The bores aren't terrible and could probably be rehoned, but is it possible to bore it larger, to say .080 or .125? How big can you go with one of these. It's a '55 block.
Also, how much can be taken off the crank? Right now the mains are at .020 and the rods at .040. Is it time to find a new crank?
Thanks
