Is your bird a standard or automatic?There are many band-aids one can apply to have a cooler running engine. I find most complaints come from owners that have not attended to the basics of efficient operation. My '57 C code operates at continuous 70 to 75 m.p.h. speed in the 190 to 195 degree range. I don't have a fancy water pump, nor a "improved water pump, nor a huge aluminum radiator (mine is off the shelf oem style replacement that I can have repaired if need be which is not likely repairable with an aluminum radiator), or even a redesigned spacer. Before you delve into other "fixes" I suggest you get all things correct in your engine. some things are not easy like excess rust in the water jackets that impede temperature transfer. Most are simply good old fashioned maintenance issues. Timing by vacuum versus timing light, functioning vacuum advance, passenger side warm up valve in the exhaust at the junction of the manifold and the attached exhaust pipe., correct spark plug range tailored to your engine's needs and condition. changing to a multi-bladed fan (mine is from a Lincoln), Is your fan drawing air though the radiator or are there portions of the shroud that are not being covered for full air pulling through the radiator. I wish all of you well. If you make multiple changes at the same time you will never really know what was the one that improved your situation the most.
You will need a smaller beltI’m going to try the smaller fan pully. Question: is there enough adjustment on the generator or do you need a smaller belt? If so, can you supply a part number?
Thanks
Good question re: smaller belt. Sellers of smaller pulley make no mention of a smaller belt. I don't think you can compare yours to a car/w A/C and alternator.Airflow at 70mph is enough to run at 50%-60% on the gauge for sure. Idle on hot days is the problem. A complete Fan shroud is a must with a new top rubber gap cover. Most problems I’ve read about is water flow at low rpm’s. The spacer directs the flow up a ramp to the inlet without turbulence caused by the casting flag( or whatever you call it) on the cast ford spacer they used (poor castings).

It is a 3 now with O.D.. Sits fine in traffic. The only time I may have a minor problem is climbing a long grade with the AC on. if I turrn the AC off then all is well again.Is your bird a standard or automatic?
Make a difference
The standard transmission didn’t have the overheating issues the automatic does
If an automatic
How does your bird do when sitting at a long red light after you have been driving 70 mph on a 90+ degree day
