Road Test of Stant vs. Shewman Thermostats

[FlatheadTed]

Most have a hole in them but if non then a purge hole is needed ,I drilled 3 1/8 " holes in one and it wouldn't get up to Temperature, The idea is to have a Radiator larger or more efficient than what's needed then the thermostats keeps it up to the ideal temperature . Hats of to Shoeman for trying to solve a over heating problem by increasing flow ,A more efficient Radiator would be one answer .
