Mr. Gasket high-performance thermostats are designed to resist large variations in coolant pressures that can occur at high rpms. Under these conditions, coolant temperature and pressure fight for control of the thermostat, keeping it from opening at its designed temperature. These balanced high-performance thermostats feature brass-and-copper construction, and open at the right temperature regardless of engine rpm.

Not Right for FORD 385/Cleveland Series Engines

Summit RacingSummit Racing Verified Purchase

Got this for my 351 Cleveland. It fits and does work but not right. As long as you keep moving it will maintain temp but if you sit idling or in traffic it will get hot. The Clevland thermostat reqires what they call a 'Top Hat' on the bottom of the thermostat which closes the by-pass port which is directly below the thermostat in the block.
