[DeTomaso] The Water Restrictor Plate Below the Thermostat

But that one is $32, what is the "conventional OEM-style thermostat that costs the same as the Windsor counterpart" that Mike refers to? I was always under the impression the thermostat with the hat was the OEM style?
In regards to the use of the block off plate no one has yet mentioned the fact that some of the aftermarket water pumps do not have the bypass port and thus probably warrant the use of the windsor style t-stat and orifice plate to prevent coolant being trapped between the t-stat and pump when engine is hot.

It’s true that since Robertshaw discontinued their 351C model, if you want a Robertshaw thermostat you have to buy one that has been customized from a Windsor model, from Marlin Jack, and due to the amount of work involved, those are very expensive indeed!

If that supposition is correct, then potentially either a Windsor or Cleveland thermostat could be blocked from fully opening if the disc in the block was solid. There is a significant amount of vertical travel when the thermostat fully opens and although I never thought about it until now, and don’t have an engine to reference to test the hypothesis, it wouldn’t surprise me if you have hit on yet another disadvantage to modifying the cooling system in this manner.
