Ported Or Manifold Vacuum For Distributor. So for you, attach your vacuum advance to manifold vacuum. the debate centers around whether straight manifold vacuum is better (or worse) to connect to the vacuum. using a ported spark advance will still allow the vacuum advance to do its job at steady cruising, but all of the benefits of idle. finding which line is the manifold vacuum is easy. Try both ways, see which works best with your car. It does not increase it remains a steady vacuum signal off idle. Manifold vacuum is situated below the throttle plates and maintains vacuum at idle and off idle. ported vacuum is situated just above the throttle plates and as you apply more throttle vacuum comes in off idle. the general answer to the basic question ported vacuum or manifold vacuum to dist? is yes. Unplug one of the lines from the distributor if has vacuum at. the manifold vacuum would simply overpower the ported imo, unless manifold vacuum is lessened some when. manifold vacuum is present at idle, while ported vacuum increases as the throttle is opened.
