Running Hot?

True. But, if you had the choice and it wasn't a full blown resto, what would you choose, a copper/brass or aluminum radiator? Just curious, because I've been told a correctly built copper/brass radiator will actually cool better than aluminum, it just costs more and is heavier.

I've seen this said before too and I think it's inaccurate. I think a better way to say it is, brass/copper cools differently than aluminum. Obviously aluminum gets the job done, because that's what all the new cars and trucks have gone to.
