Did Ford Motor Company continue to date the engine block casting until the end of the Model T production, or did they cease dating the blocks earlier?

B above… they ceased dating engine blocks around WW I

Not sure of the details on when they ceased casting dates, but mine looks like it has the casting date as 1/30/1920.

Casting dates disappeared in early 1922 for US production. Most people figure that when the change from two piece valve covers to the one piece cover, which occurred from late 1921 into early 1922, that with the change in the casting mold at that time was also when the casting date was dropped. However, I have a 1922 one piece valve cover block which has a casting date 3-13-22.

The Canadian engine blocks had casting dates throughout production.

Wow, I never would have made that connection but it makes complete sense: thanks everyone!

I understand that Canadian cast engine blocks continued having the casting dates on them until about the end of model T production there. I don't know that for absolute certainty, however that is what has been said in past discussions.
One of the model Ts I used to have had an American two valve cover block with a 1921 casting date on it.
