Anyone seen this before? 440 Lettering.

[74sundance]

I yanked this motor out of a 1968 Plymouth Fury it had never been rebuilt before.I found letters that look like they were painted on the bare casting and then painted over in the Chrysler blue engine paint.I had tunnel washed this block 2-3 times and then noticed the markings. I would have to guess that the paint brushed on under the blue washed off first and left the bare casting markings you see now.Anyone know what they mean?

Found letters on mine in same spots...was told they were put on there when engine was being built/machined to show tolerances or variances in cylinders. Mine had a D in a couple spots. Had a bunch of hemi orange markings inside the lifter gallery too.

What those letters represent is what bin the piston that goes in that hole should come from. (the engine builder knew what piston to grab)

I had writing like that in my 77 cop car 440 . I rebuilt it and put it in my 69 charger
