Very cool!
Since it's tagged as "RE-MANUFACTURED" this leads me to think it was an aftermarket offering.
No code stamp in most cases indicates deck milling may have been preformed.
Piston top may be a clue to this as well.
I came across my first ever Factory SR block last year, it was stamped as such...
