Overheating issues
It's a stock 440 '78 block with a mild cam upgrade (compcam 21-223-4) Fuel injected with sniper kit, but issue existed beforehand when I had a quickfuel 750cfm carb on it.
Thermostat:
Robertshaw 370-160 Series hi flow thermostat
Pump:
MOPAR Big Block hi flow water pump
Radiator cap is 16 psi.
Coolant is a 50/50 blend with distilled water.
Lower hose doesn't have the coil in it, but it doesn't look like it collapses when hot. (i can double check tomorrow)
Just replaced the belt a few weeks ago actually, old one was showing cracks.
As far as the radiator goes, I don't know anything about it. Was in the car when I bought years back but it managed to handle the older 440 that had over 500hp and was cooling the current block I have until about a year ago.
Moving does not improve the temperature, at best it slows it from increasing marginally.
Is your hood to radiator support seal in place? How about your lower cowl to radiator support seal?
I've never had any such support seals on this car ever. I never even had a fan shroud until recently and I only put that one because the overheating started, but years after I've had the car.
I have a temp gun somewhere, I can look for that tomorrow too.
