what is a normal Vacuum on a na car? i'm pull like 3 inch of pressure. i think it should be around 10, but i'm not sure.

Not sure exactly what you're asking. Complete vacuum is about 14.5psi.

i'm getting like 3 psi

"inches" is the on the neg side.

I believe i was getting around 15 cruising, maybe closer to 16-19 when fully warmed up. 3 is not good, lol

lol, thanks. i know that. but it does sound good thou. it sound like it has a cams in it. i have video ill post it up soon

How does the car run? Does it seem like it's lost lower or anything? That is odd to only be pulling 3 inches of vacuum, I believe it sould be around 15 to 19 like stated above. Where on the intake are you measuring the vacuum?
