Radiator has been working like a charm, however my problem ended up being the fan clutch and the FF Dynamics electric fan was not powerful enough to suck air through the thicker Ron Davis radiator. Now that I have the aluminum radiator and new fan clutch installed I have not gone over 180 degrees in 100+ Houston humidity. Pleased so far, but I would say most overheating issues can be solved with a new $100 fan clutch from AutoZone or amazon.
