I have heard a dry rear main seal make noise like that but IIRC that was a one piece rear main, not the two piece you're running now. I suppose a tight set of rings could make a noise and potentially so could a thrust bearing that is too tight fore and aft.
I'm waiting patiently to see how this turns out.

The truck engine is a 78 which should have a two piece rear main seal.
