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.
