VIN 124379N565575, pretty sure I have your DZ block.

IMHO, both stampings have been mis-interpreted.

The pad stamping is clearly December; either the 4th, 14th or 24th. December 4 is common; the others are not. 19N655151 would have been final assembled on or about June 11, 1969. It would not have an engine built 190 days prior. 

The VIN stamping is missing the 5 at position #4. There looks to be a faint 7 in position #8. The VIN is most likely 19N565575. A Z28 built slightly later has a December 4 DZ engine. It's a 386 block, cast late July.

Interesting. For data point on this thread, my 9N656767 was final assembled on 6/16/69 as per NCRS report.

I don’t know. The VIN stamping is hard to read all the numbers. Why they stamped it into a casting is beyond me. It looked to me like the number between the the 5’s was a 1 with a flag and a base that was slightly rotated to the 12:30ish position instead of straight up and down. The last number looks to also be a 1 well past the last 5, but slightly lower. I have a microscope I use for finding errors on coins I collect that I can plug into my phone, I’ll see if that helps solve this riddle…

I 100% agree that the first 3 VIN digits should be 565, not 655 by the date on the suffix pad, but I can’t see anything that even resembles a 5 before the 6.

Here’s a picture of what I “ thought” was the last ‘ 1 ‘ and also, what I “ thought” was a slightly twisted ‘1’ between the 5’s, but it could also be a 7, which is what I initially thought as well.

BTW, it’s a 386 block cast October of 68
