FWIW. Indy headed 540, Meziere remote pump, no thermostat, no restrictor, 26" alum. radiator, shrouded puller fan. Street driven.
On hot days it ran 210-215. After installing a remote fan type transmission cooler, it now runs 190-195. Removing that heat source from in front of the radiator made that much of a difference.
