TOM I used the twelve volt battery to operate the timing light and it worked like a charm. The timing was off a bit but still not the problem solver. I am back to the carb as the probable cause of all the mischief...that or the mechanical fuel pump. I drained the tank and had a fair amount of water....I should have done that first I guess but I am still in a vertical learning curve,,,still working thru the check list. Regards Tracker

Tom, SuperReal, Car Crazy ... everyone who responded to my request for help on this post...I think I found the main source of the problem : a badly curved fuel pump push rod not able to fully operate the pump to capacity at speed. The end that operates off the cam is dished in at least 1/64 ",,,,replaced it with a old push rod not quite as bad but still needs a new one, test drive up to 75 mph...ran like a champ. Bought a new Holley carb rebuild kit from C&G Ford and found a local that has experience rebuilding the Holley. My sincere thanks to every one for their suggestions and willingness to share hard earned knowledge on the maintenance on these old cars. I have gained valuable knowledge every time on this website that I have asked for help and IMHO there are no finer group of mechanics/ Car Guys anywhere to be found. Thanks again. Regards Tracker

Thanks for letting us know you found and solved the problem. Too often, we never hear if any of our suggestions helped. Be sure that a new pump rod is correct. While they all look the same, there are a number of them for different years. As you have found out, a very small difference can result in poor fuel delivery. In most cases, excess wear on the camshaft end of the rod can indicate poor oil pressure, or infrequent changes. Genuine Ford camshafts are very durable, but non stock push rods are not always so.
