Wally,
Nice to see some data which clearly shows the increased pressure out of the cast iron impeller pump, I bought one of those from Ken
Frey at a rally and will be installing it in the Paterson Stage II engine I got out of the burned coach up in Canada.
Double trouble has an aluminum radiator in it and I don't understand how it does it but it runs BELOW the thermostat setting on cold
days at low speeds!
The link below shows the coolant flow through the engine.

Does anyone have any idea why it runs below the thermostat setting?

About the car vs motorhome pumps. I've reused the original pump impeller on two remanufactured pumps. The last reman had a 3.875"
diameter open back impeller and the original GMC was 4.25" diameter and closed back. Just the impeller diameter calculates to about
a 12% increase in pressure across the pump . All ready had the original design impeller so why not reuse it.
