It has 83K on it. My thought exactly on the amount that I'm already doing. I figure it'll cost another $2K in parts and machine shop bills. Just wondered if it's really worth it/necessary, but I want it reliable and don't want to rip it out and rebuild it in a couple of years. Then the question becomes who do I trust it too for machine work. I'll need the assembly balanced in the least. I'm taking bore measurements this week for wear. I'm in east TN if anyone has a suggestion for an engine builder/machine shop. I'd be willing to ship it for quality work.
