Timing help please

Hi George,
what distributor do you have in it? The vacuum isn't bad for the cam, but I agree you need more initial. 10 is a good place to start. Also, the dial back light makes it easy to plot the whole timing curve. That's what Cracked is talking about. You have vacuum advance, which is not used during idle or wide open throttle; then centrifical advance, which is rpm based, and then you have the initial timing. For you, you can ignore the vacuum advance for right now. So you want to see what you have for timing amounts at idle, 1500, 2000, 2200, 2300, 2400, 2500 rpms, plus what the total timing is at 4K rpm. The dial back light helps. Just have a buddy bring up the revs while you dial the light and write down the readings.
