You might not have overheating issues
We had a recurring issue with occasional overheating on our RV till our new mechanic told me to use a infrared thermometer and measure the temp of the upper radiator hose the next time it overheated. ...

OP - Do you hear your Fan Clutch engage as the temp comes up? We had an '83 chassis and were lucky to have an OEM/Ford Fan Clutch that still worked. We'd hit a grade, gauge would rise, fan would roar. Come off grade, temp gauge would drop and roaring stopped. Do those things happen with your '87? I replaced our radiator with a "high efficiency" one, don't know if that changed anything, but we never overheated. I didn't do IR Heat Gun tests.
I mention OEM fan clutch because Ford no longer sells it and it seems the aftermarket ones are not as effective.
Transmission in a 1986/7 E350 would be a C6 and any temp gauge would have to have a sensor added.
