In the interest of sharing, I'll do part.

Late in the fall I learned how to find the timing sweet spot per one of the members here, and adjust the timing advance based on that. I'm not done yet adjusting my crane adjustable vacuum unit, but here's where it's at now:

Timing: 11° initial.
About 32° total at 2,800 RPM.** (About 20° at 1,800.)

With a MVA adjustable crane unit installed (my car runs MUCH better on MVA vs ported advance): I found my timing sweet spot= 23°. So with initial at 11° the idle with MVA connected is about 23°. This should give me about 54° max at highway cruising.

Now, that being said, I think my temp is slightly higher than it used to be, so I expect I'm not done playing with the adjustable advance. I'm waiting for the weather to warm up to continue fine tuning it.
