I'm working on dialing in my .030 over 389 with the performer RPM cam and dual quad.
I've got the valve stem pattern that I can live with. My question is, with the plugs starting at #1 on the cap, and the vacuum advance plugged, I am at "0" on the Balancer, with the advance canister all the way into the water neck. Idles fine, acts like it's too far advanced when under a load.

I moved the number one plug back to the number 8 spot. Plugged advance line, initial shows 20 deg on the balancer. Advance canister all the way to the drivers side. Car idles better, with much better engine vacuum, almost 12 inches. Under a load it does good, but then is hard to restart.

What do you think?
Should I go another wire clock wise? Or should I call it good enough? I ran out of day light today, I plan on tinkering with it more this weekend.

Generally you'll want to shoot for approx 14* at idle (vacum advance disconnected). I think you'll find that at 20* you'll have too much total timing (pinging).

also i would restab the dizzy rather than just move wires around, it makes it hard to diagnose later should you have another problem. what i would do is back the dizzy of a couple teeth and set it so that the rotor is pointing at number 1 on the cap with the balancer set at 10 degrees BTDC and the vacuum advance is pointing almost straight forward at the front of the car.

I git it dialed in this weekend. Moved the dist another tooth. 16 initial, 800 rpm idle, 10 inches of vacuum. It looses traction while rolling.......
