Model t engine question

[Steve Pritchard]

How rare is it to find a model t motor with what i believe is original pistons in it i took the engine apart for re-building and the pistons have the ford circle emblem on the top and the word standard next to it in cursive writing is this very rare ????

Don't know about the stamping on them, but my 1925 still has Ford original std cast iron pistons. Rare, maybe not, uncommon more likely. If they are cast iron, they would be original style, if aluminum, they would be replacements.

My ‘23 runabout had original cast iron pistons when I rebuilt the engine a few years back. They could have been replacements but that’s hard to know.
