Default 427 casting date help

Can any of you help me date this block? It is a 3916321 casting correct for a 400hp 68. I cannot find any casting date help in my black book or online for the 0nv2. The block is also stamped "truck performance S" elsewhere. Thanks in advance!

Default Bb casting date

The casting date on a B/B is located on the side of the block, just above the starter. If I remember correctly, it is also upside down when viewing from below.

The rear flange is the right location for a small block, but not for a big block.
