Attached wire hanger and pointed it over the Degree wheel zero mark.

Turned the motor clockwise, the direction it turns in naturally, and 360 degrees later where at zero again, no slop in that direction. Now we turn CCW for 360 degrees and we end up on 1-1/2 degree advanced at the Crankshaft....
All you confirmed is you have a respectable 1-1/2° slop in your timing chain - nothing more.

Did you arrive at TDC by taking measurements at .050" before and after TDC adjusting your wheel to arrive at true TDC? After you establish true TDC then you need to find the ICL by the same .050" before and after ICL and record the measurements. Then you can finally figure out whether your cam is advanced and by how much.
