Have a cool air intake, coolant in & out controlled by thermostat & exhaust out.
If you insulated the engine bay completely (you'd need to manufacture new cowling to pipe the air exiting the rad) the header and exhaust heat would quickly raise the temps around the engine and then the coolant system would need to deal with quite a considerable additional thermal load. And even if the car was driven gently the extra need to radiate heat via the coolant through the radiator would not do anything but bad things for efficiency, and may still boil the coolant.
