Its possible that a non original motor car started out as a factory blank pad and not a reground one. Therefore an acid test doesnt prove anything with 100% certainty really.

very good point. i guess it could only "dis-prove" originality...in other words...if there was a prior stamping, it would show..if it was never stamped, it would show nothing. I guess it would prove if it was the "original stamping" or not...the question being ...
when was it stamped?? Does anyone have pics of another similar dated motor?? Do the cast and assembly date seem in order?? What about the alpha-numerics...sure'd like to see photos of other stampings for comparison...
did you get the head off yet and check the broach marks????? great site guys...learning every day!!
