Default What's a ZZ4 look like?

...or more specifically, how can I tell if said engine is a ZZ4? The reason I'm asking is because I'm considering buying a C3 with a ZZ4 conversion, and I just want to be sure that's what I'm really getting. Are there any telltale stampings/markings/etc. that I should look for to verify ZZ4ness?

And if the guy whose car I'm looking at is reading this, it's not that I don't trust you. I just don't know you, and I don't know much about GM smallblocks.

Thanks in advance,

Look at where the water pump bolts to the front of the block. On the right side water pump mounting pad, the top of it should have a bunch of numbers followed by ZZ4 (example XXXXXXXXZZ4)

At least that's how it is on my ZZ3. :seeya
