OK guys - think about this! The Z-28 blocks were cast at the Saginaw Michigan gray iron plant. If a block was cast first thing in the morning, it took about 35 minutes to "shake out", 3-4 hours hanging in the cooling court, 1 hour to get through cleaning (these times are all assuming the lines never stopped - that would be very unusual). Then it had to wait in the shipping area before being loaded into a truck and shipped to the Flint Machigan motor plant. Now the block had to get unloaded, through receiving, through staging, all the way through block machining - piled on a pallet and taken over to the assembly line. Finally, it's got to be assembled and date stamped. All of this is nearly (never say never) impossible to do on a DZ block in one day. Two days - yeah, but same day - not likely. It did, however, happen occassionally at Tonawanda because the motor plant was attached to the metal casting plant - so castings were carried one pallet at a time into the motor plant.

There are REAl examples out there of both Tonawanda and Flint engines that were cast and built in the same day. Mot a high occurance, but it did happen.
