Factory 327 engine

Pulled our 63 327 apart today and found some interesting grind marks on the crank. Has anyone else seen marks like this?
The pan looked like it had never been removed. A bad casting at factory?
When we rebuilt our power-glide a few months ago it had some grind marks under the valve body and had been welded on the case by the band servo.
