Bill, How the heck have you been? Ok start with the basics, which I assume a man of your experience has done, but just to cover all the bases. First, check TDC with the timing mark and balancer. I am assuming it will be correct, but just to make sure, check it. I suspect your distributor. First thing I would do is disconnect the vacuum advance if it has one. Does it? I would line it out first without the vacuum advance. I don't run them on most of my engines. Now to the issue. It is the classic total advance verses initial advance. I am assuming that since it seems to be bouncing around on total, that you might need one spring size stronger on the mechanical advance, or there is something not right with the total stop, or the plate in the distributor is junk. Check all of that first and get the total advance to where it is stable. Most Mallory distributors have and adjustable initial advance post. The problem is that the initial is too low for the motor to run right when you set the total correctly. In my mind that is always the way to set the motor up, first get the total correct, then get the initial where it needs to be, then work on the advance curve. Move the initial post up until you get 10 to 12 degrees initial at idle with the total set where you want it. This should get you in the ball park.
