HOT running mopar 360LA

just looking at the first picture looks like top radiator hose is higher than the radiator it may have air in the system for starters. Next thing I would is take the electric fan off and put a clutch fan on.
I used to have overheating problems with temps like yours on my Demon because of a electric fan on a becool radiator. Changed out the electric fan for a fan clutch and used a shorter than stock (because of clearance) fan clutch for a Jaguar. I drive my demon 3000-3500 rpm cruising here in Texas never runs hot anymore
