My 57 210/350 runs a little hot when I use my vintage air..my current radiator is brass and looking to up grade to a aluminum ...I saw some on ebay 2 row..1 inch tubes for about 300..but also seen some with the same size tubes for 500..all are welded no epoxy..question has anyone changed over brass to aluminum and can you see a difference...any help would be appreciated

thanks
