1970 472 in a De Ville. So I talked to MTS and Cad Company today. One tells me there was not a VIN stamped on the block from the factory. One tells me the engines were stamped by 7 year old girls at the factory, meaning sometimes you can see the stamp, sometimes you can't, even if the motor is out, clean and on the stand.

For those who know, what's the story on this? VIN stamp or no VIN stamp on engines? The factory service manual says there's one.
