Mystery SOLVED! She's got forged 392 pistons in it and has been bored to 4.040! WHOA! I would say this block is at it's very max. It appears as if it was only fired up and run a little bit since it's rebuild, however long ago that was. Everything looks great though. Just need to figure out what cam is in it now. Hoping the front of the snout has marking on it. Otherwise a dial indicator might be my friend in this task.
EDIT!! Now I'm thinking, based on the markings I see on the pistons, that these may actually be just replacement CAST 392 pistons, not forged.
So that's good news then. If anyone knows what these "W" blocks can be bored out to, PLEASE, PLEASE, PLEASE let me know! Email me at
