Why no "star" on my engine
 

Why does my engine have no star?
Replacement engine maybe? Re-stamped at factory? Worker forgot to use the star stamp? Other?

Typical restamp. Probably done to match a title. Not done at factory or most likely any Ford dealer.

Here's what an original number should look like. It should start with an "A" and have a star at each end, and it was always stamped into the original rough cast, not a machined surface.

Probably a rebuilt engine that was installed at some point in time. As stated above, it was more than likely renumbered to match the title and they didn't have a star or A stamp .

Take a good look at Toms engine number,then yours.His is still in the original rough texture,yours looks smooth,from being ground off.Yours has crisp edges on the edges of the pad from the grinding,Toms has soft blurry edges from the casting molds.
