Mechanical aluminium water pump

Considering an upgrade to the OE unit.Car cools fine now with iron pump,aluminium rad,crappy plastic flex fan and single pusher out front but I'm a little concerned about the increased demand of the 545.I've had good luck on other builds (not Ford) with the cheapy,HV aluminium pumps so curious what you guys are using and have had success with?

I have the Edelbrock victor water pump on my 547 and have had no issues keeping it cool.

I have a CVF pump and it keeps my 502 cool. Try and get the style that has the round vane impeller there supposed to cool a bit better.
