nope, it never came from a merc . plenty of those came stock in trucks with that casting number. the ford casting numbers were random. also unless you look at the date code the "7" means nothing. they used C7ME-A blocks up until the early 70's then the D3TE-A block came on sceen.

C7ME translates to a 67 Mercury Engine, the -A represents an original part with no revision on the original cast.
What the cast number on the heads? I'll cross over those to see if they match with the engine block.

The FE family of engines casting numbes are very confusing and flustrating to say the least. One way of determing the stroke is to remove a spark plug and measure the stroke with a small rod through the hole.
