Usually you can get away with less rows on a aluminum radiator VS a copper/brass radiator since aluminum dissipates heat better than copper so you don't need as much surface area.

Look at most 90's and up Chevy v8's, they are single row aluminum with plastic tanks. That's what I've got and it works great.
