1969 engine VIN discussion

Starting in 1969 year model the complete vin was required by federal law to be stamped on the engine and trans. Not to be confused with casting dates or build dates...1969 year model...mistakes did happen and I have seen blank vin pads but it is supposed to be there
However, the "complete" vin is rarely seen and there must have been a reinterpretation of that law because usually it's only the last 8 of the vin on the block as I indicated in post #11. I've never personally been in the presence of an unstamped block but have read over the last 50 years about them being warranty blocks, but I'm sure on that rare occasion someone fell asleep at Chrysler and let one slip by in a car.
