19N688260 - V0725DZ is in our Z28

[vabeach56wagon]

Our VIN is 124379N658489. The engine in the car (an X33D80) is an 010 block, 4 bolt mains, original pan, July 25 assembly and 19N688260 VIN stamp (as best we can tell). The heads are 186 cast one day apart (K18 and K28).

The engine has a rear main oil seal leak and quite possibly a minor head gasket leak. We are planning to pull it and rebuild but I would prefer to rebuild a correct cast date block, leaving the pad unstamped after decking.

Our schedule is mid-February '20 for the removal and disassembly. It would be wonderful to find the at-birth block and supply this one to its rightful car.

Anyway you can post the pad stamp and vin stamp? And not in this section. Then, several thousand eyes can perhaps clarify those numbers. Someone with more experience will hopefully chime in. Because I feel that late of build car, if that vin is as you say on the block, it could be possible to have a July block?
Great the heads are a matched set. Those K dates. Are they 68 or 69? Either way, I don't think those could have been correct for your car's build date. One, too early, if 68. The other, 69, too late.  Best of luck.

Heads are Dec. 68. The pad stamp - V0725DZ - is clear as a bell. The filter boss stamp is a little tougher: that 260 could be 268 or 288...very indistinct stamping. Pad does not give any indication of block having been decked.

Neither block nor heads is correct for this car. It is a June car - delivery date of June 16 according to NCRS files. That's why I posted on the Orphan site.

Wouldn't the "K" date on the heads be November?

Wouldn't the "K" date on the heads be November?

Engine is removed from car. Appears to be a fresh rebuild, standard bore, TRW 11-1 pistons, correct crank and rods, evidence of a balanced assembly - block will be sleeved on #3 cylinder which definitely has a crack in the wall. No other damage evident. No ridges in cyinders.

19N688260 is VIN on filter boss. (could possibly be 268 but 260 looks to be the right number.
