I don’t think those holes really matter. You can see the gasket is open between the most corroded parts. I think maybe it’s the pitting closer to the cylinders at issue…
I found a 390 block on Craigslist that seems to be in better shape. If it is bored the same.40 over, can I just move everything over or would I need to replace rings, bearings and all? I’ve never been into the bottom end of an engine before.
