My Combo, Manifold Or Ported VAC Advance, We'll See...

I figure the best I can do now is to play withe the rate and amount of advance I add. I need the can weak enough to not lose timing when I drop it in gear, but maybe not bringing the full amount in at idle.

Mine might be a case where ported vac is best because of the parts I am using.

Honestly, messing with this stuff is just for fun anyhow. The old truck was fun to drive with the old 318, so the 414 ought to be a little better.
