Block Casting Identification

I looked in the Knowledge Base and didn't see this. Sorry if I overlooked it.

When I look at the back of my small block, right next to the casting number, I see a couple of little clock face things. Someone told me those gave the year and month of the casting.

Is this true? Can anyone tell me how to read them?

Thanks for your help,

Dave

The date castings are number and letter codes. The markings you mention are foundry markings that indicate the time of day the block was cast and the work shift/production line.
