Radiator Size ????

-
i have a 408 stroker ,it has a 26" cold case radiator.it cools great in 100 deg.weather.never goes over 180 deg.stopped or moving,it has 2 rows
That's a good radiator. Try as we might, but we just cannot get through to some of these guys. I know this much. My car runs great. lol
 
Now now guys we all know whose radiator is the biggest.

Now put them away and lets move on.
 
It's really the contact area between the fins and the tubes. The more surface area the greater amount of heat that can be transfered.

So it boils down to fins per inch. More is better.

Don't forget there are car engines that don't have radiators they have fins and enough surface area to keep the engine cool. (With a small oil cooler)
 
The Rat is correct when he says it's a "system".
Sure, you can have, this many tubes, that many fins, made from whatever material, but if the rest of the system is lacking, you're going to be on the road to possibly having issues.
 
My theory? Get the biggest dang radiator that will fit between the frame rails. Use a mechanical fan if you have the room, and a shroud. (My 22" was replaced by a high efficiency 28, and my opel has a 31" 454 crewcab dually radiator.)
