Where can one get a tool used to measure vacuum of the engine at idle. Not a gauge that is permanent. i just want a tool to tell me the vacuum reading of the car at idle.
i hear that 25-30 inches of water is normal. am i correct?
Whats "normal" would probably depend on your cam and other variables. I have a hand held vacuum guage that I think I picked up at NAPA or O'Reiley that works pretty well. I use it to set idle mixture on my carbs. I think my 92 with an E-cam and big valve heads only had about 16" at 900rpm and my 93 with a B-cam is at about 18" if I remember correctly.
