    Once I was talking with Flex-A-Lite and the guy on the phone said a qualty 2 core Alum rad will cool better than a 4cor rad that GM puts with BBC or whatever...
    I run a GM 4core style as the 2core was like 500bucks and the 4 core was 170...so
    My 350 and now my 454 do not have any cooling issues...so far :D
    .02c :D

    I've been told by folks working rebuilding radiators that the aluminum ones tend to have problems with the tanks leaking. Of course they say all the failures all day long, so that may not be a good sample.

    However, our trucks bodies do flex a lot, I was contemplating putting an AL radiator in mine, but decided against it just in case it flexes enough to cause problems. An AL radiator will cool better, but as long as the cooling system is in good shape and not overloaded, copper/brass will work fine.
