thanks ,,,  I'm going to have the trans rebuilt so I will pull engine and trans ,,   I did run a compression test all looked good ..    

I’ll suggest a cranking compression test on all the cylinders.  Be sure to run the compression test with the throttle blocked in the wide open position.  That will rule out almost all mechanical issues at which point you are left with carburetor and ignition at the top of the list.

Ted,   thanks for the info ..   It's the stock holly carb(rebuilt)  I did pull the sight plugs and check the float adjustments. I pull the bowls off and and the metering vavles are closing when you blow into the gas inlet.  the only thing I can think is perhaps the timing chain jumped one tooth or shared the keyway???  look into the carb as it was running and no gas running in....    I pulled the intake and heads looking for a gasket issues but all looks good ..     the vavles are carb up black shoot ...   

I do appreciate you taking the time to help

I didn’t see any mention to which carb you are running.  From your descriptions, it could be flooding.  I’ll suggest looking down the throats of the carburetor either during running or right after it quits and see if the discharge nozzles are dribbling excess fuel into the engine.  If it’s a later model Holley, then removing the sight plugs in the sides of the bowls will give you an idea of if the needle seats are not adjusted correctly and/or simply bypassing additional fuel.

after a lot of cranking and gas + starter fluid it will ruin for a few minutes and than starts to miss and quits ..    I tried adding a little gas down the carb and it wants to stop...  If I try to pump the accellorator   it wants to quit   

Are you running an original glass filter with stacked brass washers? Mine would clog up after a few minutes of running. You couldn't see any particles stuck to the filter but when i would pull it, blast it with carb spray and re-install the car ran fine. I'd drive it for 10 minutes and it would clog again with a mud like film that you really couldn't see........... I would run a new filter and follow the advice on previous posts. If the car starts and runs for a few and then stops, it is not timing chains, valves or ignition.

If your compression checked out ok and it does run well when you do get it started, then it has not jumped a tooth.

is there any way of telling if the timing chain jumped a tooth without pulling the cover ???

It's not getting gas, everything else is fine,. Is there a fuel filter in the line between the fuel pump and carb? if so change it, that's the problem.

Troubleshoot it.  When it won't run, pull a plug wire and observe the spark.. Blue = good, not the ignition electronics.  Red = bad, possibly the ignition electronics, maybe engine or distributor grounding.
