Aluminum as a metal will dissipate heat much more quickly than the metal that a stock radiator is made of...copper I think.
I ran an aluminum afco radiator in my 90gt with a twin turbo setup and had no problems whatsoever. I think most new cars now come stock with aluminum radiators.
You may also want to look into redline Water Wetter if you are worried about cooling. It is an additive for your cooling system that will aid in cooling. I used it in my 300hp trans am, my 624rwhp gt, in my 88 modded vette, and I plan on using it in my 66 mustang......on average it dropped the temp 10-15 degrees.
