Now that's the best bunch of BS I've ever heard. It's time you came out of that fog you're in T A. The strength of aluminum has nothing to do with heat dissipation. I think you best listen and read what George K has said. I doubt if you're an engineer as he was.... he knows his stuff and seeing he does, the smart ones of here listen to/read what he says. Charles is knows his stuff too.... you see he has owned his GTO since it was new. And I bet he knows every nut, bolt and little quirk that can go wrong. As a matter of fact, he doesn't have an over heating issue. He doesn't use an aluminum radiator, and neither did Pontiac.

Sorry Don that your thread has taken a turn away from your intended purpose. I applogise for getting into this mess on radiators and leading things astray.

I'm just gonna sit back and watch from now on.....
