Maybe you need a multi pass radiator. Do you know what is in the car now; single, double; triple pass?

The difference between radiator in and outlet is 10°C (50F). Not enough I would say. Maybe making the pump more slower? It was running on a ratio of 0.8 slower than crank, currently 1:1 speed. Any ideas? 10 Liters are circulating.
