Were you able to find the build date? It in a small chunk of metal that is machined flat on the front pass side. Usally there is something in front of it making it next to impossible to find on many late model cars. If you got and old block or know someone tat does its alot easier to find it on a cleaned block out of the motor. But its located right where the heads bolt to the block in the front pad. If you cant find it im sure someone has a picture.
I have not messed with many of the early blocks. I may be wrong about the casting clock location. Its been on every chevy i have ever worked on but got to say i never ripped into an 57 engine.
