another total timing question

To add to the above.
Initial timing (aka Base Timing). Usually set below the start of mechanical advance rpm.
Mechanical advance: the timing added. The 11 stamped slots will allow roughly 22 degrees.
Total Timing: Almost always refers to Initial+maximum Mechanical Advance.
However, the factory engineers were sometimes more clever than hot rodders and racers appreciated. Some distributors have a very heavy secondary spring so the weights don't hit the end of the slot until 5000 rpm or higher. So, just pick a reasonably high rpm, like 2800 or 3000 rpm and just be consistant in using it.
example: Set the initial timing at 600 rpm to 10 degrees BTDC. Using the distributor you have, expect Total to be 5+22 = 32 degrees. At what rpm it hits 32 or even 30 will depend on the springs.

Vacuum advance: Usually not used when setting initial. On an original engine, you'll find some use manifold source and others a timed (aka ported) source depending on year and engine. The ported vacuum is sourced so it provides zero vacuum at idle. Otherwise it is the same as manifold vacuum.
The vacuum pod's adjustment does not change the degrees added. It only effects when the pod starts (and finishes) adding advance.
