Stamp looks good to me. I have a 12B LA built Z and the fonts are similar. My VIN is stamped on the pad too. Is this one?
I was told that the Vin was stamped near the oil filter. That was another question I had.. when did or did Van Nuys move their stamp off the pad like Norwood ? Also, just curious.. I know there's a window that blocks were cast and used but due to it being near the turn of the new year and with the Holidays and work weeks being shortened is it possible that a Z could have a block casted 2 months prior? Just throwing it out there..
Not sure when the shift was from the pad to the oil filter area occurred but my engine was built 7 days before yours and it's on the pad. Makes it nice to read.
