IMHO, I want the largest capacity radiator that will fit in the available space, a well designed shroud, mechanical fan, properly sized water pump and thermostat and the A/T cooler independent of the radiator.

Will other combinations work? Probably. Will the same combination that works marginally in Seattle work well in Phoenix, probably not.
