So was this something done after a certain year? Or just by a certain block plant? I've never seen it on a factory built engine. The engine Chris is talking about was as built when new, Bearings were dated 2-72 so it is a virgin engine.

Ok thank you
This is a 72 model block
I have a 68 - 70 - (2) 74 model blocks all trucks blocks like this one and none have this machining so was just curious.
