All,
Finally got back to the Pantera today.

- Removed both vacuum hoses from the distributor and plugged them.
- Set 3,500 RPM timing to 35 degrees, blipping higher it advances 
another degree or two maybe
- Then check Initial timing at 650 RPM and it's 10 degrees
- difference between idle and 3,500 RPM = 25 degrees

The mechanical advance may not be putting enough advance in.

- Then checked vacuum retard, it's working, retards timing between 6 and 
10 degrees.
- Pulled retard vacuum and plugged again
- hooked up advance vacuum
- No advance at idle.  Vacuum advance -begins- to move timing at about 
1,200 RPM
- At 3,500 RPM, the vacuum advance is adding 10 degrees to mechanical 
making a total of 45 degrees

Is that good or bad?
Why?  How?
Help....
