Hi, someone please help me, I am a carb idiot and just can't figure out my problem.
I have a ZZ4 350, TrickFlow heads 2.02 1.60, A comp cam .474 .474 gross lift 107. lobe C.L. MSD 6AL plus box, MSD mag pickup dist, Blaster coil, air gap intake, and a Holley 650 D.P mechanical secondaries in a manual Chevy k1500. 4.10 gears.
I just can't seam to get this thing to stop popping out the carb on moderate to heavy acceleration. i now have the carb set very close to out of box spec. with 10 deg. advance on the dist. and heavy springs in it.
It seems like any change I make to the carb adjustments and timing adj. improve one problem but make something else worse happen. I don't believe i have any vacuum leaks for I read 15-18 in. of manifold vacuum at idle.
Any advice? I am open to any suggestions, I will try them
