Some engines like ported, some like full time manifold vacuum. In any case, use the vac advance. Your engine will run better, and cooler.
dist. advance set-up
I bought a MSD dist kit and it has full adjustment for the advance curve.
What RPM does the advance need to begin and how much total ? I think the limit is 28* mechanical . It starts easily w/ 12*initial.
10.5 to 1 w/781 heads,427 with 279*/290* Crane cam , QJ on alum intake -maybe 3310 Holley later, Hedmans ,3.31 rears.mostly street cruiser.
I will add a 6AL box with the dist. install also.
All new and haven't got enough miles to put it thru the paces yet with the original point dist
