I have a new TDC degreed balancer with the engine rebuild. Yes, the new dizzy has 24 degrees advance, just like the Davis unit had and initial mechanical timing NOW is at 40 degrees BTDC without the vacuum advance for a total of 64 degrees all in.. Yes, I do know how to set the mechanical and vacuum advance as well as degreeing the cam at engine rebuild. Timing was set using a Craftsman adjustable timing light.
One thing I did not mention: When the car died with the Davis unit, I was at 65 mph and the engine died cold with a thump. Car had to be flat bed towed home where I determined the coil was bad and the module was below specs. neither of those components would have caused the thump when the car died. I might assume that the new timing chain MIGHT have skipped a tooth but I can't confirm that unless I pull the front cover/ water pump assembly.
