My kid recently bought a '52 panel with a 350/350 combo. The seller told us that we would probably need to install an electric fan as the engine could get hot in slow traffic. He was out in a more suburban/almost rural area. Well, traffic in the big city can get very slow very quickly and there was an issue with overheating. So we installed an aluminum radiator with an electric fan attached to a shroud. The install seem to fight us all the way even though the radiator and shroud were made for a '47 to '53 AD. A couple of examples: The fan was too close to the engine pulley so we moved the radiator a little more forward in the radiator support. Clearance good. The original lower hose was 2 inches at the water pump and 1 1/2 at the radiator. The new radiator is 1 3/4 inches. Finally tracked down the proper hose. Now works very well, keeps things cool and looks good.

It's a small world, but I wouldn't want to paint it.
