I purchased a plastic fan from Applied GMC. Supposed to be the latest a greatest.
So far I cannot find out what Fan Clutch to use with it. Jim is not answering my emails for some reason.

Use the one that you had that was working with the metal fan blade. See how
that works for you. I presume that you were having some kind of malfunction
in order for you to want to change a good working system for an unknown
one. If the clutch cycles too often, and your engine is in tune and is not
overheating, good luck getting your new combination to work for you.
Been there, done that and went back to the metal fan and medium duty fan
clutch. Your combination WILL DIFFER.

Installed the plastic fan at Bean Station. Used the fan clutch that was already there. I have no idea which one it is. I have made four trips without any noted problems. Temp gauge indicates normal operation. Pretty hot on the roads down here in Lower Alabama. Your mileage may vary.
I also installed Frank Jenkins's full size fan shroud at the same time.

The severe duty and heavy duty will both do the trick.
I have used both with my nylon fan with excellent results.
Being that it a few degrees warmer than hell here in Texas I tend to gravitate towards the severe duty clutch.
The fan is so quiet you are actually going to have to pay attention to hear the fan engage.

While I did not have an overheating problem, I purchased one of the new fans from John Biewirski at the GMCMI rally a couple years ago in Wisconsin. Installed it with a new standard duty Delco clutch. Fan is much, MUCH quieter and the temp holds rock solid on 190 degrees (my thermostat), even in Alabama heat.

I sent Monte an off net email earlier in the week. I suggested that he use the OEM equivalent AC Delco 15-4208, or 15-4216, or the 15-4947. All of these are the same "Heavy Duty" specs as the OEM GMC clutch. I also gave him the 15-4644 number in case he wanted the noisier, and faster "severe duty" clutch. It turns out that AC Delco used different part numbers for the same clutch depending on which car manufacturer it was going to. (Buick, Olds, Pontiac, GMC, etc.) Now 30 to 40 years later with very decreased demand, they have consolidated the numbers down. So you will find many of the original numbers are obsolete. It makes stocking multiple numbers unnecessary when a single number will do. If you look up a 15-4947 you will see it listed for multiple years of Olds 455 cu in. engine powered cars.
