Yeah, I know what you mean. I'd have to get creative with alternator mounting, but that shouldn't be a problem. Do you know offhand if the 70+ AC w/p pulley would align with the outer groove of the non-A/C crank pulley??

No I don't think so. If you think about the belt routing on a SB with AC and PS. You have dual belts that go alternator, Compressor and crank. Then you have WP,crank (outer third groove)PS pump.
Boy sure are a lot of posts for a simple solution. Put it back to stock. Proper type fans blade, proper fan clutch, proper shroud, Thermostat, radiator cap, change to a recovery system overflow like all modern cars. Should have no problems. Fans only do work below 40-45 mph after that they are just a drag on your engine. Momentum forces more air thru the radiator than the fan can.
You are on the right track going with the smaller pump pulley. See here:

Not sure what model you have but many were made when leaded petrol was available. The lead helped cool the combustion process.
Smaller pulley. Depends how creative you are & what tools you have. I have many times gone to wrecking yards to find a pulley of the diam I want. I then machine off the pulley section & mate it a factory pulley by machining/welding. Simple job for a machine shop.

We are all here because we are not all there.
I do not have a pic
The factory A/C crank pulley is a monster, very rare and hard to find.
Check out March pullies I believe they have a small diameter water pump pulley.

The thing that I don't get is why would Chrysler make the pulleys rotate at such a slow rate to begin with?

They worked fine for what they were designed for.
U can get smaller aftermarket pulleys. This 5 7/8s x 2 7/8s. Not quite what ur looking for. Kim

Thanks Kim. Do you know who makes it?
Sorry I don’t. It came with a motor I bought. Don’t see any markings on it. Kim
