Last month I did heads and cam on my car and got it to run real good, this last weekend i put 24's , a new MAF and a edlebrock intake manifold on the car, Now the cars bogs down and backfires when i mash on it. I never touched the distributor so i dont think its the timing. I thought it was a vaccum leak so i hooked up a vaccum gauge, it reads about 7 or 8 which is really low but i know the cam lowers it just dont know ho much. I can sneak up to high RPM's at quater to half but at wide open shes says no. Thanxs

it runs perfect at quarter and even up to half throttle

the cam is a stage one trick flow

Did you use any type of sealer with the intake gaskets? I suspect a vac leak - spray carb cleaner around the base of your intake where the gaskets are and see if she changes in idle speed. Good Luck

a stockish motor should pull near 20" hg at idle. with a cam, i would NOT want to see below 10". is your power brake assist lacking with 7" of vac - i would not be surprised. knowing what the characteristics of that cam would help, but i doubt it is a characteristic of the cam - i like Brown 5.0 Fox's (sorry bud - I had to ) idea with checking for leaks.

good luck.

I had that problem...it turned out to be my fuel filter. i also ran the tank pretty dry so the pump must have picked up some crap from the bottom of the tank.
