I have an 82 Z-28 with a built 350 and the 4 speed manual, I played with the carb today(mech secondaries I think) and did get it to idle pretty steady but now it's back to stalling, surging at idle then stalling,bucking like hell at low rpm cruising, and I cant tell if it's backfiring or if it's the massive *** cam the engine builder put in it. Any idea's? Also I'm using mid length headers and a full accel distributor complete with super coil.

Try going through this http://www.thirdgen.org/techboard/ca...ey-tuning.html (Holley Tuning)

If the ignition timing isn't right, nothing much you do with the carb will fix that.

Do you have the cam specs?

Yeah it's .632 gross lift and I think he said 312 duration it's a full race cam

Oh yeah I cleaned the carb up with some carb and choke cleaner and a tooth brush (venturi's were black and filthy) retarded the timing a few degrees and holy sugar honey ice tea she gets up and hauls, puts ya sideways in second and the burbling is the cam it sounds like a top fueler
