Triple check the firing order to ensure you don't have 2 wires swapped. There was another thread where swapped wires was the culprit.
Timing Tab (HELP!!!!)

t5 just reminded me make sure your wires aren't arching off the headers or a split in the wires somewhere.
went through and re-adjusted the lifters on the only side i messed i with. Took them all to clatter and then did a 1/4 turn tighten. Tried to drive the car and it will go but if you try to give it gas fast it will spit back and cut off. Also checked the plug wires and they seem to be just finebowtie81 said:
Really at a lose at this point. Any one have any new ideas before I try moving the dizzy a couple of teeth?
sounds dumb but make sure the firing order on the dizzy is going the correct direction!!!..just went thru this with a friend...i finally figured it out after 2 hrs of jacking around!! he had correct firing order but wrong direction..correct me if i'm wrong but if i remember correctly clockwise looking down @ dizzy
Ill check it out and make sure they are on in the right order. never had them off the cap but anything is possible.
Does anyone think the carb could be the problem right now? Like maybe its was damaged in some way from the flames spitting back through it when the timing was way off? Its a Holley 4160.

No cant say that I have. Not really 100% sure how to check it all since I am still in the process of learning. Any suggestions on how I go about checking them?bowtie81 said:
there will be a sight plug on each of the fuel bowls, take one out at a time and with the car running the fuel level should just be below the hole for the sight plug. If it isnt you will have to adjust the level with the needle and seat, and they are at the top of each fuel bowl.
Adjusting Float level>> http://www.holley.com/data/TechService/Technical/Carburetor%20Tech%20Info.pdf if you tighten the nut it raises the fuel level.
Unless your Carb is older than 1992 it will have a Check Valve that prevents the Power Valve from blowing during a backfire through the Carb.
