I messaged him for the VIN stamp by the oil filter and he sent the attached picture. He also said that he would sell it separately without the 1178 crank or the connecting rods.

what are the markings before and after the block stamp??
I was wondering that also.
I have located the M22 for same vin. Appears block is legit.
