I have a 1956 Chevy 210 with a 350, 700r trans, vintage air. On days with the temp at mid 90's temp runs at around 211 with ac on cruising around town. I'm concerned when temp gets 100+ it will run too hot. It has a flex fan to pull air and an electric fan to push. Any ideas as to what type of radiator would be good to install to help run cooler?
