Strongly agree with this point. The radiator is only one piece of the cooling system puzzle. You also need to make sure the water pump plate is spaced correctly, the correct (or optimized) pulley sizes are being used, the proper size fan, fan clutch, and shroud are in place, and the factory air baffles/dams/seals are present. All of those things play a part in keeping the engine cool.

For what it's worth, I've been happy with the Cold Case radiator in my '66 GTO. I appreciate that the tanks on them have an appearance that is closer to stock than some of the other options on the market. You won't fool anyone who actually knows what they're looking at, but they do blend into engine bay a bit more than others.
