Not meaning to bust balls, but your post has my eyes scrambling.
I spell lousy and my diction is in the toilet. So bare with me as well.

A tight fan clutch? MoPar has the viscous unit. Cools like crazy far a stock unit. It was on all the Hi-Po cars.
How well does the radiator flow now. Is it cloged at all. You'll need the best flow you can get through that radiator.
The stock water pump may not be up to par anymore due to age. I had a flow cooler unit. It did wonders for temps. I didn't like the disc on the impeler falling of though. It needed a better, more permement mount on the impeler.
I dont understand "no trans fluid in rad also "
Water wetter is a good idea.
Running lean will raise temps in the engine. Richen that baby up.
If your problem persists <sp> it may be internal.
Years of use may have left to many deposits in the engine.

Be sure that you have the correct water pump and pulley for the AC you are running. The AC pump has a smaller impeller than the non-AC and the pulley should be smaller than the crank pulley (about 2/3 the diameter). If you have a shroud, get the clutch fan of the proper length, or shim the fan to have about 3/4 inch of the fan in the shroud, and the rest out of the shroud.

Backing off on the timing and richening up may also help a bit.
