You are right, I think the key is to keep the rpm low enough that there is no mechanical advance.

The engine is timed at the 502 HO spec. I am getting 3600 @ 36 with the vacuum disconnected. The dist that I am running gives 22 degrees of mechanical. So 36-22=14 is the initial timing that I have set to. Nowhere can I find any reference of the initial RPM.
