Looks suspicious to me, Charley. Block surface texture looks very different under each stamping. And what the heck does '168626897' mean https://www.yenko.net/ubbthreads/imag...s/confused.gif

Re: Engine stamping...comments ?
 

The block pad looks like it's been decked up to the V. The #s don't make any sense. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Re: Engine stamping...comments ?
 

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.

The stamper apparently thought that the year should be represented with two digits - '68 vs. just an 8 https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Re: Engine stamping...comments ?
 

The V022 looks almost the same.

I think the 2's are different fonts.

Re: Engine stamping...comments ?
 

Charley, can you post a picture from the front looking down the deck surface to see if the deck surface level changes.

Re: Engine stamping...comments ?
 

No I can't but the deck level does not change. Those are orig broach marks.

It is an LA built Z28. https://www.yenko.net/ubbthreads/imag...mlins/flag.gif

The motor and trans were ass. the same day pretty neat! And it's a M-20 that's good to get the 302 outa the hole.

Re: Engine stamping...comments ?
 

This is off my Norwood build Z. The VIN is on the side by the filter.

See my post here Engine stamp data base

Re: Engine stamping...comments ?
 

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

Re: Engine stamping...comments ?
 

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.

Re: Engine stamping...comments ?
 

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.

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?

Re: Engine stamping...comments ?
 

The cars vin is 124379L526897

Re: Engine stamping...comments ?
 

And yes Lynn, this has been a exercise to see different answers. The car belongs to a friend and he has owned it since the mid 80's. It is not a restamp.

Re: Engine stamping...comments ?
 

I've come to the conclusion that any engine stamping from any car can be posted on here and there will be at least one person (usually several people) who will believe it's a restamp. And I'm not picking on anyone in particular, as I don't even check to see who posts what, it just would seem that it's impossible to find a pic of a VIN stamp thats ever been posted that doesn't have at least a few sceptics of its authenticity. Seems like something is always either too perfect, or not perfect enough, etc. I guess spotting restamps must not be a 100% science....yet.

Well at least the drunk guy on the line got the last 5 digits correct.

Pretty interesting, and just goes to show there are exceptions out there. Back in the 80's when they were making Chevettes and Pontiac T100s (talk about your pieces of crap) at the OKC plant, they had a car come off the line with Chevette emblems on one side, and Pontiac emblems on the other.

Must have been a MONDAY car. Remember the days when they gave you the build date of the car when it was ordered. You dreaded that it wasn't a Monday car.

-------Funny you mention that, Lynn. My wife once went to pick up her new company car and recieved a half Horizon half Omni, but split front (Hotizon) to rear (Omni). We always called that car the Horomni. It may have had a dual personality but it actually was a good little car.........Bill S

Re: Engine stamping...comments ?
 

Just like the orange ZL1 that was pin striped black on one side and white on the other! It was the 1,300 mile car, 4 speed with chambered. Look at the mis-matched decklid to tulip panel stripes on the 26 mile LS6 and the upside down SS emblem in the grille! Same mistakes on my original LS6. Not much quality control back then.
Mark

Re: Engine stamping...comments ?
 

You're right Mark,quality control needed to have someone looking over their shoulder as well,..there's no "CHEVELLE" grille emblem on the 26 mile LS-6 either.
Exterior ornaments are one thing,but you would hope they would've crossed their T's & dotted their I's when it came to brass tax items like the CON VIN stampings.

Re: Engine stamping...comments ?
 

It was actually a Thursday car, It should be an 03B car and probably has an LA W/O number somewhere near I520. Started down the line on 3/13/69 late afternoon, probably hit the GM assembly area (where the VIN would have been stamped on the body on Monday 3/17) and the engine area (body drop) on Tuesday 3/18. So the engine and transmission would have been stamped either late Monday or sometime Tuesday.

03B car. Block is cast B 18 9

Re: Engine stamping...comments ?
 

LA built cars have a w/o number stamped on the lower right corner of the trim tag that consists of a letter and three digits like I520. It is how LA kept track of car bodies inside the plant. The letter is equivalent to the bay the body was scheduled to be built and roughly corresponds to the day of the month in this case I = the 9th working day of the month, and the digits equal the 520th body scheduled to be built on that day. Note that the build day letter does not always correspond with the calendar day, ie the A build day is not always the first working day of the month.

Re: Engine stamping...comments ?
 

trim tag from same car https://www.yenko.net/attachments/194622-DSC02229.jpg

Re: Engine stamping...comments ?
 

Weren't making many Camaros on that day, I've got a trim tag from a Pacecar 34 VINs later with a I605 W/O number.

Re: Engine stamping...comments ?
 

How about anything prior to I125 in an 03B? https://www.yenko.net/ubbthreads/imag...lins/dunno.gif Anything else occur alike this in that week?

Re: Engine stamping...comments ?
 

That statement wasn't meant to be taken literally. LA built 3 different Chevrolet models (I think) and about 650 to 700 cars a day, so one would expect about every third W/O number to be a Camaro. But nothing says the bodies had to be spaced evenly throughout the day. The first 100 bodies of the day could have been all Camaros, or all Impalas, or whatever, they could have been scheduled to be made in batches or single units, you would have to follow the W/O numbers on the other models to know how they were distributed on any given day.

Re: Engine stamping...comments ?
 

Ahhh, now THAT makes more sense to me!

Based upon my knowledge , in theory, there would "APPEAR" to be hundreds of Camaros rolling off if you went by that!
I state that as when I did the math and the compared the #s and VIN's , for VN in that time, that would have this.
So there could be thought that 200-250 Camaros built per day?

To me that seems a bit high if you go by the # of units made in total, included in that total would be the Norwood cars for the whole years' totals!

Wouldnt it be more correct to state that there were about 100 Camaros built each day at each plant, roughly giving about 350 cars a month, ending up around 17,200 per Plant for Camaro's?

Was there any VN cars that had a number(not the letter) greater than "Example": I599 ?
