If you have the big thermostat pocket (mine was in the surge tank flange) and want the large flow a Chrysler product thermostat fits.The large thermostat that is available for Ford has a large body but the actual valve is tiny.The Chrysler (Dodge Plymouth) is the correct large body size and has a large valve like a Chevey. Works great ,you can buy the optional grades of thermostats that have the air bleeders and if it fails it will fail in the open position.My understandings is that FE's need some heat .180° sounds more in the ball park if you have a cooling system that can keep up with it
