I plan on running a Muncie now. Check this thread out. http://www.jalopyjournal.com/forum/showthread.php?t=660536 I havn't finished it yet because I'm not 100% sure which trans I want to run, but the muncie will bolt up by drilling new holes and machining an extended piolet bearing.
This block has a cracked sleeve though. The sleeve is about $45.00 and I can do it myself. I have a 392 hemi I sleeved all 8. I know what you mean about the pits filling up. I've seen some nasty **** that ran.
