vacuum advance! do you hook it to ported / timed vacuum or manifold vaccum?
this is a long standing argument and conversation topic across the entire classic car community!
@thejunkyardnecromancer has called out me, @UncleTonysGarage, and @ThunderHead289 for being WRONG about using ported vacuum?
well if you want an ultimate performing experience I suggest using ported vacuum in combination with a curved distributor that has had its machanical timing limited so you can run higher initial timing!
with manifold vaccum when you hit the gas or go Wide Open Throttle the vacuum drops down close to zero and consequently your vacuum advance does as well.
wirh ported vacuum you dont have vacuum advance at idle, so if you run the initial timing higher with machanical when you hit the gas you will not lose all that timing to get you off the line!
also if you want a detailed video on how to dial in your vacuum advance check out @UnityMotorSportsGarage and @DavidVizard as they have videos showing you how to do the things I explain in this video!
