The easily cure is to install a high-flow N/S assembly in the factory Q-jet. All of my kits for the Pontiac carb come with them. If that doesn't fix the issue start looking at a restricted fuel filter, fuel pump, collapsed fuel line, loose clamps, etc.....
This sounds about right "If it takes off fine going to WOT pulls hard then has issues at high RPM's or top of 1st or 2nd gear it's another problem.". Raining here the next few days but as soon as I can get out, I will test again and post my results.
