It would be hard to hide, but an air dam below the radiator could make a big difference in cooling. If you can create a low pressure area below the engine it will "pull" more air through the radiator and out the bottom. Without the low pressure assistance the air sort of puddles up under the hood.

Another possibility is to add an oil cooler. It's a quiet and subtle modification and it will help removing engine heat.

It may be possible to change spark timing and fuel/air mix to improve overheating as well. The settings were determined with fuel used in the '50s. Today's gasoline is very different and in some cases you can advance spark and / or change mixture and see an improvement.
