As Brad pointed out, the thermostat has more to do with engine warming than cooling. A fan shroud, a higher volume fan, a smaller WP pulley, or a bigger (or less restricted) radiator would help.

There was no fan shroud factory and ounce the motor got up to 160 it wouldn't (open/ close) cycle. It would stay open therefore not very good cooling. The 180 worked fine it it.
