Will this radiator out perform the Ron Davis aluminum? My Bronco is running 200 to 210 on hot Louisiana days with the Ron Davis & aluminum water pump. Airflow doesn't seem to be the problem.

We generally prefer the aluminum radiators for their heat transfer ability. The Tri-pass radiator should perform close to equal, and we would not expect it to better or worse by much. We do usually look at air flow and like to use electric fans when possible.
