I have a pretty rough idle as of late so I checked my vacuum and I am at 11 with a needle that barely jiggles. I am running a 92 460 bored 60 over, headers with multiport EFI and over sized valves and a milled head. My cam is:Voodoo part number61602. 219/227 @ .050" lift. I know what to expect out of a vacuum reading in a totally stock engine but with this cam what should I expect for vacuum at idle and how steady of a needle should I expect?
I have sprayed carb cleaner around the intake and the throttle body base to try to locate a leak and found I can get the engine rpms to drop around several of the bolt heads? Seems odd but I thought I would bounce it of you guys so what do you think?
