Running Hot?

Just to clarify, this advice applies for aluminum radiators. Copper/brass rads do better as 3 and 4 rows in that order.


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.
