Re: Where does my distributor vacuum go?

You want it hooked to a port that increases the vac as the rpm's go up. If you hook it to a manifold vac port it will be at constant full advance in the timing. Just start the motor and use a vac gauge or hold your finger over the port. Raise the rpm it should increase the vac as you raise the rpm.
