Cooling the 440

My thoughts exactly, not moving enough air at idle. It is a 26” rad and removed a copper one. It is running much cooler, but just looking for perfection and no worries about overheating and more enjoyment going for a ride

Have you got a box fan? Maybe set it right in front of the car and see if that helps it cool down any. Then you'll know for sure.
