Clay,
What a great thread!! I think we have the same type of block. I don't have the ribs like you do on the passenger side but there isn't a date or anything else on that side of the engine.
I tried to decipher the stamp below the
oil in/outlet, on cylinder #1, and it's hard to see but it looks like 8 (or 9) J 2. There is a big E above those (or below depending on how you look at it).
Can you tell from this stamping what date it is????
I took pics but they all came out blurry. I'll try again.
Thanks,
Charmer
