So as most of you know, Pontiac is famous for overheating! This brings me to the question now, I have a 1967, 326 firebird and wish to change the radiator from the old brass 3 core to an aluminum. Anyone know where I can find a 3 or 4 core aluminum that will accept my original shroud and clutch fan with out spending an arm and a leg? I really do not want an electric fan on it. I have looked every ware and no one can guarantee the fit for my original shroud.
