The above gobble-d-gook (sp) is the factory listing for a 73 BGT.
Dist#, Vac Adv #, Vac Adv characteristics, static and dynamic timing.
This is out of some tome I dug up.
The early cars had a 10 degree mechanical. I'm pretty sure your later car
should have lots more, but I did not research that. The vac adv
characteristics you give are also early, suitable for a ported vacuum
pickup. The 73 uses manifold vacuum. I think you have the wrong
disturbutator.
