Radiator construction

Just seen this thread and still want to read all the replies first but my initial thoughts from what I remember ...aluminum holds more pressure than brass...is lighter weight and is cheaper. I think that brass dissipates heat better or I should say faster but I don't really have any evidence per se to back that up ...it's something I was kind of told a long time ago when I was about 17 years old.
I only need a single row aluminum radiator for 410 inch small block, and I like that as opposed to a heavier multi row brass core.
