henry, you will never win. you are trying to argue intelegent logic to a caveman.

had a 41 pick up with stock 8BA. drove san antonio to atlanta and back with skips pumps. had stant 180 degree stats in going. ran 185 except when in traffic and then it heated up quickley in traffic. took stats out before trip back to san antonio. ran cooler 170-175 except when in traffic and it heated up quickley in traffic. ran around san antonio for several weeks and had exactly same thing when stats in or out. took off skipd pumps and reinstalled new C&G pumps and with or with out stats things were the same, except did it not heat up quite as fast as with skips pumps. at all times i had the recomendedmixture of antifreeze per skips instructions.
bigest problem seemed to be traffic with low air flow through radiator. did not have shroud or high volume fan, just stock fan. put electric fan in front of radiator with a temp sensing switch to turn on electric fan at 195 and off at 175 and that cured overheating in traffic. recored radiator was in truck at all times that had 7# coolant recovery cap setup for coolant recovery with recovery tank.. never lost water due to recovert system.

have a 50 sedan with gm crate motor, BW 5 speed trans, 190 stat, walker radiator, walker shroud, 7 blade high volume fan, AC. car runs at just below 3/4 on gauge freeway or traffic. key is high volume fan & shroud. has a coolant frecovery system.

41 pu had a 59 motor, 8BA motor and a gm 350 motor in it. AND with all 3 motors in it it had the same recored 4 tube radiator in it. all 3 motors had the same slow speed overheating problem that a pusher fan in front of the radiator cured. i feel if i had been able to get a shroud and high volume fan in there i would not have needed the electric pusher fan.

get a good airflow through the entire radiator with a shroud. use a high volume fan to pull all that cool air through ALL the radiator, and probably either pump will get enough water through a clean radiator to be heat exchanged and allow you not to worry about overheating.... don
