Thank you everyone, for your input sorry it took so long to report back. Thank you Brian you hit the nail on the head with the Float settings, they were way off.

I took the carb apart and found floats not set properly. Set to specs for carb, cleaned and put back together. The car is still cold blooded takes several attempts to start when cold. Shuts off, I pump the gas and its starts shuts off...etc. after manually closing the choke the car stayed running. I got it to operating temp 185 Degrees, in park I stepped on the excelerator, it spit through the carb and shut off, I pumped the excelerator one time car started and shut off again. Everything is the same as in the first post. Timeing, getting fuel, fresh gas, no vacuum leaks (if I place hands over the carb it will kill the engine) "vacuum leak test." I have worked on over ten Chevy 350 engines, valve jobs, cam replacement, timeing chain and gear replacement, overhauls. In over 35 years I have never had a problem restarting an engine after service. Again PLEASE HELP! THANK YOU ALL!

You must live someplace were a functioning choke is required (not needed were I live except maybe 5-10 days a year). You are describing a malfunctioning choke (it is electric on the Edelbrock carb) Be sure you have an adequate power supply (to heat the bimetal strip through resistance), ground, and it is set for some where in the middle so that it will operate (you get it operating first then tune the amount of time it runs to your climate).

The choke activates a high speed idle cam and enrichens the fuel air mix by restricting the amount of air that gets into the engine (producing lots and lots of carbon monoxide in the process so be sure it is well ventilated and not sitting in your garage at the time it is warming up).
