Cooling question

Hey guys,I have an 87 Ram 50 with a 360 la and 727 which I was told was pulled from a 70s dodge motorhome.Im assuming along with the swap they also installed the massive radiator from the motorhome,So massive in fact that they removed the front grill,Bumper,And hood latch to get it to fit. Would I be okay downsizing radiators? Thank you
