My 53 Willys Station Wagon has a 360, To cure its hot problem I Louvered the hood ,This Helped the most. Took out the uncoated headers and got coated ones, This was the second biggest improvement. One of the first things I tried was to put a second elec fan in front of the radiator , it made thing a little worst, it blocked more air flow a speed I also have a 2core alum radiator ,mechanical fan ( Tried Electric didn't work)
