Manifold Vacuum Advance what am I not getting?

Yes,
Turk by definition an IC is a very inefficient device. You cannot overcome that obstacle, only work with it.
Learn to read. I said MVA is one method of giving extra timing [ post #24 ].

So all those racers that lock their dists, have done for decades, they are all wrong too??????

Oh, now I get it.........they should have built The Turk Special: an engine that had 12.3:1 CR, a cam with 255* @ 050 duration, tight 107 LSA, tunnel ram with dual 800 carbs. So folks this engine is the fix so that you do not need a lot of idle timing!!! [ Wait for a sale on 800 carbs.]

Newsflash for Turk! That engine will want a lot of idle timing & if you understood the combustion process involved, you would understand why.....
