I've heard bad things about high flow water pumps, actually moving the water too fast for good heat transfer, both picking up heat from the engine, and getting rid of it in the radiator. I'm suggesting that you might be able to actually see the flow via the cap direct into the tank (mine is off of a remote neck), or pull the pump and inspect the impeller, and the attachment of the impeller to the shaft.

Dave, that's a very good point, too, and one I had not thought of. A set of under drive pulleys could also be the source of reduced coolant flow.

'61galaxie,
Have you shot the system with an infra-red heat gun? It would be interesting to see what an accurate direct readout says for temps on your block, top tank, bottom tank, heads, etc., just for grins. Your local auto parts store might have a loaner?
