It's the coolant pump!The Milodon pump, like the Weiand pump, is designed to operate without a thermostat. The recirc passage of the Milodon coolant pump is not drilled out. So until the thermostat opens up a bit, there is no coolant flow through the engine.
Not good for the engine.
You have two three choices
(1) remove the thermostat
(2) remove the pump & drill the passage open.
(3) while the pump is off, replace it with the Flow Kooler pump.
Also, the Stant 13468 thermostat is nothing like the original thermostat. The original thermostat, made by Robertshaw, has been sold by many companies, always identified by the number 333. I would strongly suggest replacing the Stant 13468 thermostat too.

Awesome! I know he had replaced these (pump and thermostat) upon recommendation prior to engine build. Also had the plate put on.
I’m guessing the pump itself would not be causing the issue of continuing to slowly rise up till 230+ at idle given once the thermostat opens it should stop the recirc challenge as it will fully flow to rad, etc, correct?
It does, however, seem that the thermostat would be an issue at idle or while running, and could be a series contributor to my problem. I did not realize the Stant 13468 was not high flow. I want to look for any Windsor based thermostat with a 333 in it, correct?
