Just wondering if anyone can tell me a rough vacuum numer on a b303 cam? I am showing 8in at the gauge.

Also is it normal when you blip the throttle at idle for the vacuum to momentarily decrease towards zero and they go to a higher value of vacuum?

I am still trying to find that missing link that is making my car crawl.

I'm getting between 12 and 13 in at idle (950 rpm). Always wondered if that was a good number... :cool:
