I would normally assume this engine is in car 124379L626897, correct? Only problem is the last LA built Camaro should have VIN sequence 531163.

My gut feeling is:

Engine and trans stamped by the same "gang held" set of numbers. The first "6" is high in both, and the last "7" looks slightly bigger, but the two stampings definitely look consistent. Could this just have been a new guy (or hungover guy or ___________ [fill in the blank] guy) on the line that just totally screwed up the stamping. I have heard of numbers that were one digit off from the actual car, but nothing this screwed up.

Does the car VIN have any correlation to these stampings?

Charley, is this a test to see what kind of assinine explanations we can come up with?

The cars vin is 124379L526897

There's no plant designation. and the first 6 is should be a 9 it's upside down. The first 8 should be an L because I think by 2-20 of 69 norwood cars had the vin by the oil rail.

It also looks like Flint used the number 0 & the letter o,as well as two different type set number 2's.

The deck surface and engine assembly date and code look OK to me. I'm seeing more and more "deep" broach marks in '69 and '70 cars than I usually see in '67 cars...not sure why that would be, but it is definitely very noticeable on many Tonawanda BB's. I can't comment on the VIN derivative as I don't follow '69 Camaros.

I also think that improvements in digital cameras are giving us much more definition than years past and this is raising concerns unnecessarily in some cases.

Here's what I've heard about broach marks. As the broach machine lost its sharpness, the cutting edge or edges were sharpened. When the broach was sharpened, they would surface the hi performance blocks first, this could mean that they would surface the four bolt main blocks first since they were going to have a higher compression.
I don't know if this is true or not, but the broach certainly would wear down leaving different types of broach marks. I've always noticed more of a pattern on big blocks than small blocks.
