Did production 1909 motor blocks have casting dates?
Let me ask the question a different way. Can someone owning an early 09 verify that their early block DOES NOT have a casting date?
I'll bump you back up. I am curious about this detail myself. I wish I could give you an answer, but I have read conflicting "facts" on this myself over the years. I do know that a few of the " "09" engine blocks I have seen were modified later blocks, even though some were claimed to be genuine. That I know does confuse this issue more than a bit.
I hope a couple people that know more than I do about the earliest Ts can tell us what they think.
