Hi guys, carrying on from my PCV question the other day, this is my Holley and manifold - front and rear views.
On the rear I have been using the full manifold vacuum for the booster, the one blanked off, should this be for the PCV ?
On the front I have been using the small bottom port for the Vacuum advance on the dizzy, is this correct ?And on the front there is a port unused with a black bung on it, what is this for and would it be ported or full vacuum ?
