For the DRB Cobra the build manual recommends a Commodore 1979 to 1983 radiator with 3 or 4 rows of tubes.

I went to a radiator place a while back and the guy there said, "yeah, the 4 core is best, the 5 core is no good as not enough air flow"

Yesterday I went to my local radiator bloke, he said "Why do you want 4 core? Not enough air flow. You should get a 3 core for street driving." he went on to say "4 core is OK for racing where you will get plenty of air flow but not for the street"

What do you guys think. Who's right?

I will also have a condenser (air conditioning) and have an auto trans so will be relying on the radiator for that too.

Also the local guy says a aluminium radiator will cool better. I'm sure I read some place that aluminium radiators are stronger but less efficient at cooling. Which is better at cooling aluminium or copper?
