1971 Radiator question

I would like to replace my wife's radiator in her car so we can attempt to run the car on the street some times for cruse nights. The thing is that we don't want much more wight in front of the car so that it doesn't effect weight transfer when we race. Both outlet and inlet are driver side on a 440. 11.2 compression 10.4 et car. so it runs a little hot . what would we be able to get away with just a stock replacement but aluminum 22in?
