My car is in the sig and that is all that I know has been done to it! In other words it has NO Computer control to it now at all

At low RPMs the car is stumbling like crazy, but once it gets up a little it runs terrific
Anyone have anything in particular to look for?

My ignition system should be fine, I pulled a couple of plugs and they all look super
Have new MSD wires and the cap and rotor are less than a month old, I was having the problem before the changes

Could it be in my carb?

85 camaro SC
305
Holley 650- wonderbar (weld in type)- Flowmaster- K&N open element- Smog Pump removed- AC removed- Power steering removed- Interior removed- All computer controlled wiring removed- Heater box removed
Still to freakin heavy

 

Is your 650 a VS or a MS. If it's a VS, I will say the spring for the secondaries needs to be stiffened up a little, I went through this same process with mine at the track, if I stalled it up a little and had to wait, the car had a serious bog when launching. I put a stiffer spring so the secondaries would'nt come in so fast-problem solved.

 

Tell us more about your ignition. What type of distributor is it?

 

igniton

HEI vaccum advance distributor out of some old chevy truck
Ac Delco cap and rotor
MSD wires
Autolite plugs gapped @ .035

VS carb w/ K&N Filter

 

You sure would'nt hurt anything by gapping the plugs at .45 or .50 with your HEI.
