Guys its not a carb issue, yesterday I pulled the motor out and the lifters are ground and the cam is trashed. I will get some pics asap. Pistons and cal walls look good though, still need to check bottom end.

This may not help your immediate problem, but when I recently got my car, the original 4GC carb was really working poorly. I ran a double dose of carb cleaner in a tank of non-ethanol boat gas, and by the end of the tank, the carb was clean. I run only "recreational" non-ethanol gas in it now, runs like a new car. In my area, the fuel is available at all "WAWA" gas stations, same price as premium.
If you car is missing, what do your plugs look like? That may help you zero in on your problem. Could it be one plug, or several plugs fouling or a bad wire or cap? On a Chevelle I had it turned out the fouling was due to a non stock big named fuel pump pushing too much fuel. I replaced it with a stock pump and the fouling stopped.

Just saw your post. I recently changed to a Street Dominator, from Holley. By their computations, a 625 was the biggest I could use on the stock motor. I bought a refurbished carb from them on-line, it was under $300.00. I gave them the engine specs, and the rep said it would come out of the box set up and ready to run. It did, I just put a spacer under it to clear the linkage, set the idle, and it runs great. I agree with the others who have said to check the timing. I would take a few minutes, check compression, manually set timing from TDC with the plugs out, and check electrical again. Engine sitting for a long time, spitting through the carb can be a hung calve, too. Compression check will find that. BRO is spot on, ethanol destroys old fuel systems. I run non-ethanol 90 octane in the car, same price as premium, no problems.
