My 340 bare block

Is that the original block to your car? The reason I am asking is that I have been searching for my original block from west central Indiana for the 69 GTS I bought in 1995. If it is not your original, do you mind posting the VIN? As far as the mods, I have had dozens of 340 blocks and have never seen anything like it?!?
The block is not original to my car , a '69 273ci . Believe it is '73 . But I will post vin within the next day . Sourced the block locally though . Sheldon il. 60966 .
