Alumimum does not shed as much heat as copper and brass does That being said a good three or four row desert cooler type stock replacement copper and brass radiator would be my choice now that I have ran both types in cars with a lot more HP than 500 in the Mojave desert in the summer time




That's what I was thinking, who told you it had to be aluminum?
Properly tuned I bet a 22" would be fine.
