Cooling observances and hypothesis

the flathead eng has a design problem the exhaust travles through the block. to comensate they put large rads. witched helped. these cars were never made to be driven at 60 mph for a long time. the speed in the 30,s on the highways was mostley 35 mph .you are driving a 75 year old car & expect 2017 performance,

Frank, you're probably right. However, you may want to call and ask. I have a 6 volt Pertronix unit in my 1931 Model A. Just a thought.

Not sure where you are from, but that was not the case were I grew up! Kansas did not even have highway speed limits until sometime in the 50s! All of the old Fords were driven at 60+. My parents were constantly driving back and forth to Colorado and all over Kansas and it wasn't at 30 mph.

I have two 8BA's, '49 & '50. Stock radiators, stock 160 degree stats, Sierra antifreeze, half and half mixed with water. Speedway water pumps on both engines.
Last year driving to Tulsa and back, 93 - 98 degree outside temp, ran normal temp.
year before that Brainard, MN, 95 degree outside temp, ran normal temp. I read a lot about improved water pumps, improved stats, water wetter, etc. If things are correct
I think there not needed. Maybe the older Fords do need help, I have always had 8BA blocks.......My '50 has a real gauge on it and it runs l75 degrees on a hot day.
