Well like was said already, you need a ported vacuum source. But if I were you I would try hooking it up to a full-time vacuum source. Only difference between ported and full vacuum is the ported vacuum will give no vacuum at idle and less vacuum at lower throttle levels. If you hook it up to full vacuum, at worst you'll get a high idle speed and it may want to ping or stumble at tip-in. But with your base timing set at only 9*, I would give it a try.

no, at worst you'll get an unstable idle as the vacuum changes and changes the idle speed. especially as you go from park to an in gear position



Well, thanks for everyones reponses. As for the two responses above...earlier last week I did actually hook up to the full time vacuum. Idle speed did jump a couple hundred rpm's in neutral, but in gear speed seemed about the same, I think. There wasn't anything unstable about it. Didn't jump around, going up and down. It just stayed steady. With the old distributor, the tach needle would flutter at idle and kind of waunder, but as soon as I gave it even just a little throttle it would smooth out. But with this new dist, it is rock steady.

Also, I haven't heard any pinging or detonation on accel, however, throttle response, especially when cold, really sucked. When I left school on Friday, I punched it to pass someone and it just fell on its face. It wasn't that bad with just the new dist and no vacuum advance. So I'm wondering what my best options would be. Leave it disconnected, hook it up to full time, hook it to full time and adjust the timing up or down?
