I am think that further pump improvement can be had be rebuilding a pump with the curved vane impeller and using much closer than EOM tolerances for the pump vanes to the pump housing. I just had a pump rebuilt in this fashion and the difference in tolerances is significant. I cannot document any improvement in coolant temps at this point with the new engine. In my opinion, a custom rebuilt water pump over normal aftermarket pumps has similar advantages to a custom rebuilt carb over an off the shelf Holley. Off the shelf is purdy good, but custom rebuilt is better. 

The Edelbrock pump has a cast curved vane impeller, with cast backing 
plate. I'm really satisfied with my pump.
