I've never been really happy with the cooling performance of my current set-up. It's a Griffin aluminum radiator, 6-cyl position, no tranny cooler, with a stock replacement water pump and "high performance" 160 degree thermostat from Summit (forget the brand). It will go above 180 even in cool weather, cruising or stop & go, and when it's warmer, 190-200, with excursions above 205, especially when pulling off the freeway. This spring I removed the engine driven aluminum flex fan for a puller electric that pretty much covers the radiator, didn't really change anything.
I'm thinking the water pump is the culprit. I picked up an aluminum unit with backing plate, hope to install it this evening. Before I do, I'm going to flush the system good & proper as well. Picked up another thermostat (supposedly the best one available) to try as well.
Sure hope this takes care of it.
