My carb is an Edlebrock 1406 (?cfm)
Intake Manifold is also Edlebrock and its the Dual Plane #2701
I readjusted the idle to were it sounded normal (no tach) (no rumpity rumpity) and it checked out to be 13 1/2 Hg on my vacuum. Fairly steady with maybe 1/2 Hg variation.
Distributor vacuum is connected to the left side vacuum of the carb and my vacuum gauge inside on the column is connected to the right side vacuum port on the carb.
