Vacuum advance
I'm trying to tune my .030 over 455 vacuum advance. I have a "Mity Vac" that can put vacuum into the Vac. advance can and see what it's doing while idling and watching the timing light. I figure that for 14 degree more I can add about .83 inch to the 36 mark on my balancer and check the timing with a buddy in the car reving the engine to about 3000. Or do I need that? I can also see when it starts to come in. When should it? I have a Crane advance unit.
