The original block would have a VO stamped and then the assembly date then CTB for standard shift motor. Or CTC if a automatic. Example V0626CTB. The partial vin can be stamped 2 different places depending on if it's from vannuys California or Norwood Ohio. Norwood stamped on rough cast side of bellhousing near oil filter. Vannuys on the front pad and rough cast area. Your block surely appears to be a decked replacement 350 block. Stamped by the rebuild possibly. Also if your vin matches the legible partial vin and block cast date is in line with the Trim tag date it could be the the original. Better pictures of the block pad stamp, cast number, the cast date partial vin may help take this further. If you can post some better photos of the block stamp that can help?
