Brake clean is a nice cheap spray solvent for cleaning the oil bath if needed, however you should just be able to pour out the sludge, wipe with a rag, then re-oil. IIRC correctly, the oil is simple engine oil, was SAE 30 for the time.
If the truck was converted, the gauges may have the little resistors added to the back side, however simple way to tell is that you should get about 100-125 RPM durring cranking. However again, back to basics, do we have fuel, ignition, and compression?
