I have a '55 235 engine in my '37 p.u. My question is about the radiator. I removed the original radiator and put in a new aluminum radiator that is for a 39-40 truck . Is it considered a pressurized or non pressurized system? Do I need a recovery bottle or just a overflow line. Or should I just leave the radiator loose. The cap that came with the radiator is a pressurized cap. Any help is appreciated.

I would consult with the radiator manufacturer for their recommendation. The engine should be able to handle pressurization equal to what Chevy was using in 1955. The primary advantage of a pressurized system is that the boiling point for the coolant is higher.
I would recommend that you not connect a heater that was an accessory in the late 30’s. Those are designed to work with non-pressurized cooling systems.

To use a pressure cap ou need to know if the filler neck it designed for a pressure cap.
Adding an overflow tank is another story.
