I have a K78 DZ short blk, it is a 3932386, and the front pad has V1I14DZ and the vin number is  19N557648.  I have had this short block for 10 yrs.  I have a 02D Z/28 that I have owned since 79'.  I wish I could find a late Jan or early Feb Block.  I also have a D109, 3956618, V0411DZ blk.  The vin on it I cannot read.

My 02D X33 has a V1I19DZ motor. It is an LA block with the VIN down by the filter. Unless I can find something very close or exact I won't change.

About a year ago I purchased a short block assembly that was date correct for the car I am restoring.  I have an 11C built car (19N545911) that was supposed to be a real deal pre-X Z.  (2 years and many Benjamins later, I still can't prove or disprove - to my satisfaction - whether it is/was a Z, but that's another story.)  The motor is a 386 block, casting date J 17 8, and an assembly stamp V1019DZ. If it makes any difference on the bogus meter 10-19-68 was a Saturday. The VIN stamp is difficult to read and could only be seen with a magnifying glass after I got the bare block back from the machine shop. It's by the oil filter and I'm pretty sure reads 19N533186. Does this sequence fit with the motor build date? Also, weren't the early VIN's stamped on the engine pad and later moved to the area above the oil filter to save time pulling the alternator on the assembly line? The motor has been rebuilt from carb to pan, and from a component standpoint is every bit a "DZ".  I just need to know if the block is a factory original.  Out of frustration, I may end up be selling the entire lot, and even though I purchased everything as "authentic", I can't, in good conscience, sell it that way if it isn't. Any help would be greatly appreciated.  And yes, not surprisingly, I'm considering buying some ocean front property in Phoenix.
                                                                                                    Thanks,  Steve

Looks like 2 days from cast date to motor assembly. That's how mine is spaced, cast date is I 10 8, and engine assembly is V0912DZ. My car's build is 10B, 2nd week Oct, so about 4 weeks between engine assembly and final install in car. Looks like your engine assembly to final install is about 4 weeks as well. Date timing seems plausible/reasonable to me. My VIN is stamped on the pad next to the build date, not by the oil filter.

His post is 9 years old but you bring up an interesting point Jimmy.  Something I've been throwing back and forth with a couple of members.  With his car being an 11C build and the vin at the oil filter, and yours a 10B and the vin is on the pad.

Mine is a 12D and the vin is at the oil filter as well.  At some point in that Nov/Dec time frame Norwood made that transition.  I've seen 2 other cars very close to my build with the vin at the oil filter as well, that tells me this practice was getting pretty consistent by then.

However the JM book briefly mentions the change happens sometime in January.  I tend to believe it was happening a little sooner as the evidence suggests.

I think JM's book is from 2008 or so? Maybe info on issues like this has become better understood or defined since the last publishing.

You're probably right.  I just bought the book after I joined this site and I think it was already a few years old.
