I'd run an all aluminum rad as big as I can get in my car.

All you can get in LOL ,it looks like the battery tray is in the way of running a 26" in my 69 fastback so I went with a 22" 3 core champion for my 410sb but if it proves too little I will relocate my battery and go 26"

ya i know its espensive but the stuff is the best on the markit . so to me its worth the money to be to keep the over heating gods at bay. nothing i hate worse then when you are in the town and you engin that you just spent ten grand on is over heating becuse we went cheap on one of the most inportant part to keep the engin alive the cooling system . so to me its worth every cent but on they other hand iv never run afco rad what temp are you seeing.????
