I think I would re check the timing chain, just a hunch. BTW it will run one tooth off hence 50 or 60 degree advance. You are compensating for the tooth with the distributor! The engine will not have the power expected but it will run! I had an old Pontiac with the plastic timing gears that jumped time. I turned the distributor till it ran and nursed it home.

On the timing issue: We've done pretty much everything you mentioned. The Mallory is brand new. Not sure about the Mallory advance post you Talked about. I'm just helping out trying to figure out what's wrong. No Vacuum advance, all mechanical. And I can't believe the timing marks are Off a tooth or it wouldn't run at all. Problem is, we tried a brand new Mopar electronic distributor and it Does the same thing. A guy that works in a local shop and knows a lot About Mopars was helping us also. He said that he's had a couple of Mopar engines do the same thing and couldn't figure out what was Happening. He had one in his boat that he said was running about 60 Degrees advance with a light and it ran perfect. This motor sounds and seems to run good with it showing 50 degrees Advance with a timing light so I'm stumped as to what is causing the Problem. Must be the Mopar gods causing it because we used a Chevy coil bracket On the intake, I don't know. The guy picked up his car yesterday. He's going to run it on the street For a while and see what happens. ---- Please address private mail -- mail of interest to only one person -- directly to that person.
