In terms of temps, warming up a little when stopped is pretty typical. OK as long as it does not get too hot.
Warming up while driving would be more concerning to me. With good airflow at speed I would expect the temps to hold just over T stat temp with a healthy system. Speeding up the water pump may help but I wonder if there is another problem. Radiator not sufficient or maybe water pump not sufficient? Did Glendale sell you the radiator?
The current radiator is a Griffin unit. Other than a blown head gasket, which would be pretty evident, I can't think what else could or would be the issue---oil & coolant look normal, the car runs well and there's no weird noises or anything else coming from the engine. And I agree---the engine should be in the 180-195 degree range at speed but it's not. A 5 mile trip in Summer weather & I'm already at 195 & climbing.
