John, more information about why you're asking would help us help you. What vacuum readings are you getting? Is the reading steady or does it fluctuate? Fast or slow? Probably most important, what is the problem? Symptoms? Is the engine totally stock (especially the cam)?
396/402 Engine Vacuum Reading
Hey guys...I recently got a 72 SS 396/402 and my father-in-law and I have been working on the engine. It's a numbers matching car, but someone did a poor tune-up on it sometime before we got it. The question I have for you is---
Does anyone know what kind of vacuum reading we should get on the car in park at idle (700rpm)? It's an air injector reactor engine, if that makes any difference.
I know this is kind of a specific question, and my knowledge of engines is layman at best, but my father-in-law is very good, and he's having a tough time getting this thing tuned...
Any feedback would help immensely, and if I need to provide more info than I did here, let me know...
Thanks again everyone for all of your help...It means a lot to a newbie owner..
