Can someone please school me on this block example and tell me what I have?
I’m trying to find an appropriate date code and casting for a Z-11 build. I have a large number of blocks to sort through. This one happens to have a fresh +.060 bore size.
The date stamp makes no since to me.
Right side rear 311
Block casting #. 3857656
Left side above oil filter. Upside down J 19
X block
