Moved some stuff around in the shed today, including that "some day" project engine. With it where I could see, I found these numbers...oil pan rail: (star) L725220 (star) and on the mounting ear: AAC
6OAO
3H17A
The last four digits on the mounting ear look like a unit number - 1983, Aug. 17, 1st shift. There is also a 4.4" cast (not stamped) in the block just below the head on the right side. It's a naturally aspirated engine, and assuming the 4.4" refers to the stroke, it's from a 6610, correct? This one has the cross hatching on the side of the block, while my cousin's '83 7710 does not. I'll have to check his buold date again.
