stumble problem
 

ok my problem is after i do my burnout the car just stumbles won't clear out when i pull up to the light i can't even set the transbrake because it stumbling so bad. the engine is a 13 to 1 383, with a 850 mighty demon thanks for your help.

To avoid a bunch of speculation on your tune up. I would borrow a friends standard holley carb, if you can, that is proven reliable and give it a try. You may discover that your demon is the carb and not your tune up. The other option may be checking the float level and being sure that you are not running more than 7PSI of fuel pressure causing the flooding condition.
PS. I am glad that you got that trans/ torque converter spacing problem behind you?

X2, I think your needle seat are sticking. Maybe trash or PSI problem.

Where is your fuel pump mounted. I had that prob with my Camaro and after lowering the fuel pumps from the trunk down under the car it was all good. They rely on gravity to feed them from the tank and a burnout will draw fuel away from the pumps when the burnout stops.

x2, sounds likes its to me also

Might also be that air bleeds clogged up. That will make it run rich.

well the fuel pump is under the rear of the under the fuel cell it's a 82 camaro. i took the car off today and clean it good but won't be able to test it untill friday at the track if it still act crazy then it time to find a new carb. hey thank you all for your help.
