360 running hot…very hot

A quick solution would be 17 inch 7 blade fan for starters, one inch from the rear of the radiator. I would try a fixed blade first, maybe a clutch fan later. Remove the blade guard and space accordingly. I would probably go as far as to mount the transmission to the core support behind the grille just in the path of airflow.
