Radiator trivia

[Mrturner1]

On an aluminum radiator, is it actually better to only have 1 or 2 rows as opposed to a big 3 or 4 row brass OR aluminum radiator? I was talking to a guy about radiators because I am in need now that my factory 3 row brass one has a leak near the inlet snout, as well as 20 years of rust and other buildup on the coolant tubes. This guy told me that I should get a 2 row aluminum radiator instead of a 3 or 4 row aluminum one that I was about to buy, and his reasoning was that with less rows, the aluminum could dissipate heat better than a bigger radiator could. Is this true? I'm looking at Champion Radiators because everyone on this website who has one loves it. The Champion website has a 2 row aluminum that is said to cool up to 500hp, and they offer a 4 row aluminum that cools up to 1000hp. That is the opposite of what this guy told me, but I usually get a lot of good tips from him bein's he's been drag racing and building cars for a long time.

Even if a 3 or 4 row is overkill for my truck, I'd like to know the answer to the question I'm always learning and appreciate all you guys for helpin along the way
