I'm gonna guess that it's a '67 or '68 [Model Year] and that the "UA" you see is a bad strike for UH, UR, UP, or UN. "J 12 7" = Oct 12th 1967.
I have an engine in my '68 C/10 Stepside that's stamped F0627XAE. I know it's the original 292 engine, at least since I bought the truck in 1973. I also had a core 292 that I ran for 25 years, pulled out of a '67 ex-Forest Service stepside that's stamped F0626UH.
My "UH" is on the charts but I could never get a read on "XAE". Then again, yours could be a perfect UA and our knowledge base is too limited to learn more.
The '67 and '68 Flint L-25 292 L6 blocks were good pieces, and the 12-lobed crank was the perfected design.
