Griffin says aluminum is better, they only sell aluminum. U.S. Radiator says copper/brass is superior over aluminum and they sell both. Talking to a HVAC expert, he says copper/brass coils last longer than aluminum coils.
I'm leaning towards using my OE radiator. Aluminum might look "pretty" and all but my only question is will the OE adequately cool my engine with up to and beyond 500hp with a 190 thermostat and A/C?
The OE radiator is not designed for 500 HP... unlikely a stock radiator will work well for you if you actually use the HP. You need an upgrade in capacity... it can be the material of your choice - either can work - but needs upgraded I think. Good luck!
