Not for the lack of trying, Patience is a virtue. Sooner or later we're going to figure this out.
Other questions are,
What temp thermostat are you running?
Horizontal core or vertical?
what year and kind of car is the engine in?
I could be wrong but I think there was a separator plate involved on the water pump on pontiac engines.
Was it left out?
Thermostatic clutch fan or flex?
Correct radiator cap pressure?
What type of temp gauge?
Not testing your mech. ability and you've probably asked yourself these questions already but maybe I've hit on something you might have missed.
From your first post I really don't see why you have this problem.
