I wouldn't be adverse to changing oil to suit the current weather. On my very low mileage cars I changed it in the Spring for the Summer and again in the Fall for the Winter. I use 10w/30 for Summer and 5w/30 for Winter. I can see the benefit of more use specific oil for that "bad" 440 though. But I'd park it in Winter before I'd trust 50w to actually flow.
