Here's the photo of the Milodon HV (30% increased flow) aluminum water pump (#16235) with the recirculation by-pass.
Also picked up the Robert Shaw 180F t-stat and these are set to be today's project. I'll report on the benefits in a while....Julian
Julian, THANKS for taking & posting the pic. Thats the first time I've ever seen the back side of the Milodon pump. If your Pantera is currently running a Windsor style t-stat, you'll be pleased with the results of runing the proper style t-stat.

Julian, Cna you inspect the impeller. is that a disc over an impeller with curved vians or is it a disc over the standard blender style finns ? Thanks, Ron
Ron, thats a round disk welded to a paddle wheel.

The "hot tip" on the Ford impeller was to reduce the OD to reduce high rpm cavitation (makes bubbles).
Doug is referring to the cast curved blade impeller that Ford sold as a replacement for the standard impeller in the oem water pump. Reducing the impeller OD OR milling away every other vane was employed for motors running at NASCAR rpm (4500 to 8500 rpm). That was not a hot tip for street motors. Reducing the rpm of the pump by altering pully sizes would have been equally effective for the NASCAR boys. Automotive water pumps are designed to operate over a certain band of rpm, exceed that and the flow curve takes a nose dive.
