Thermostat on new 4.6L

Would anyone know what thermostat is used on the 4.6L mustang cobra motor that RF uses? Any help is appreciated.

Thanks
Bob.

bob,according to sean hylands book he recommends running cooler than standard at 185 deg f instead of 200 deg f , but not to run too cold. he also says to drill small bleed hole in thermostat .hope this helps.
