I'm a noob at this but hear me out. Using ported vac requires lots of base timing for a clean idle. This forces you to reduce the mechanical advance of the distributor to prevent too much timing at higher rpms. Manifold vac gives you clean idle, allows lower base timing, so you can use more of the mechanical advance curve. It also increases timing during cruise. |
