I have an upright Ron Davis radiator. The fins are epoxyed into the side tanks. It developed leaks in all 4 corners during two years of use. I was able to fix the leaks. I had a 350 Chevy motor. No shrouding front or rear. A small cfm electric fan. Never had an overheating issue. When running 60 mph the motor ran 180*. I am currently changing the motor to a 427W. I will use this radiator with a larger fan and will shroud the front and rear, and hope it will work.
