Pictures are sometimes worth a thousand words. But from the only identifying feature that you mention (8BA) says that it could be a '49--'51 car engine.

Except for the paint, looks like my 50' 8BA. 239ci., 100hp. I do not know of any ID#s to be found inside. Sure looks nice though.

Everdently you had a head off to see the crosshatch on the cyl. Did you measure the stroke? If it 3-3/4 it's a Ford. If it's 4in. it's a Merc. Those no. stamped on the front don't mean anything to us, only the guy who stamped them. If you deciver those no. on the top it will only tell you when the engine was made at the factory. Walt
