Aluminum radiators
Horsepower essentially equates to heat so the more power the engine makes the higher up the food chain your gonna have to run radiator wise along with the rest of the cooling system components, I have no idea the power you will be running and I have mid 900 hp and the Wizard with 2 inch and a quarter cores is what you want.....Griffin also offers that same type core configuration. If you are more of a stock or mild type build then I suppose a Champion or some of the other cheaper radiators would work ok but no actual experience with them.
