How to ID a Small Block Engine Block:

That is a very useful thorough link.
Three things caught my eye:
a. there were only two shifts for casting
b. Shifts were only 8 hours
c. no mention/explanation was given in this link for the reoccurring large #6, seen after the casting number, and also found on front valley wall and elsewhere on the block

I read here recently and unconfirmed that the #6 designates the casting station
