1971 340 Build - Choosing piston rings dilemma

Yes well good luck, hope the tough Mopar blocks reputation doesn't let you down. But I'm surprised that the machine shop didn't suggest that you sleeve those bores. If they were the only two bores that were stopping you leaving it at a healthy 030 or 040 then that would have been an easy solution. Or even if it had been three or four bores like that, then sleeving, if done properly, and then machined down, is a great way of restoring a block with doubtful walls.
That was discussed. He gave me a couple of options to choose from so I did the right thing and went the cheapest most risky way! Lol
