Decoding/Numbers / Re: Any 3932388 DZ Engine Pads close to V0425DZ?

We discussed this block-exchange program here several years ago - it was done occasionally to ensure that neither plant had made any machining changes that would compromise the Service requirement that either Flint or Tonawanda blocks were interchangeable and would accept the same common replacement parts in the field. It's theoretically possible (but HIGHLY unlikely) that one of those Tonawanda-supplied interchangeability audit blocks could wind up built as a DZ engine, including drilling/tapping for and installing the 1/8" NPT oil gallery plug above the timing cover.
I'd need a whole bunch more evidence before I'd believe that Flint V-8 built a DZ engine, without the oil gallery plug, on a Tonawanda block; too many ways to fake just about anything.
