In the 9 digit ,or 1's our identical ,my 4 closes at the top. I shot several pics of the VIN ,and based on the camera angle the stamping appears very subtle to deep. I sent Ed B. copies for the data base ,but I'm not posting. Hate to see "my" engine on Ebay one day.  04D build date.

Yes, who knows. I see that last digit is very light. Looks like a "9" ? How can you hit them all super deep and then have one that barely shows. What the hell!!  ??? ???   I need a few more entries here, and some more explaining before I tell my buddy weather or not to pull the trigger on this car... Danny

Nature of a gang stamp. Individual stamp shanks tend to deform over repeated use, plus the holder itself allows some movement of the individual stamps - they are usually held in place with a key or wire, and will shift slightly that allows some irregularity in the finished stamp. I'm pretty convinced the stamping looks authentic, characters look good, alignment is within the range of normality in my estimation; the only question mark I have is the suggestion of decking. It could very well be that if the rest of the block surface has been milled, then the shop that decked it did the right thing and kept away from the pad stamping. My opinion -

I agree with z28z11. I compared Danny's pics to mine and the characters are identical in detail. Except for my 4 touches at the top. In another pic of an authentic block ,one of his does not ,and his first one appears to. Lighting and camera angle can play tricks on your eyes looking at machining markings. Seeing as I'm the only one to ever pull the motor in my car ,I know mine are legit . I think it's real safe to say 1968 Z28's are. :) Looks like Danny's buddy's are also. IMO
