451 overheating, even when moving

So I'm gonna measure the rad temp in different spots tomorrow, and I'll be bypassing the heater core while I'm at it. It doesn't do anything but make my feet sweat as it was moved to above the transmission hump inside the cabin and there is no blower anyway.

Unless anyone has good reason to keep it. This car ain't gonna see the road after our thanksgiving and before may 24 anyway.
