The Vin Stamp has a misstamp at the end. Was this common? 70 Norwood Trans AM

[LeighP]

Yes, mis stamps are fairly common. my 77 T/A had a ghost stamp on the engine number itself where the stamper must have double tapped, and it bounced.

Does that stamp have 29N at the front?

Yes, it begins with "29N"

This isn't the original engine for the 70 TA then?

I believe it is. Block Casting # 9799914, prefex WS 0585920

[RATTCRUSHER455]

I WOULD BET MONEY THAT BLOCK IS A RESTAMP

Is the 122912 the last 6 numbers of the car's VIN?

[johnta1]

Looking through my EUN page, it appears the EUN is within range of the engine and the date code.

I'm wondering if the stamper didn't screw up the '9' along with the other digits?

Does it look like a '2' under the top '2'?
(looks like it may be something else)

The area around the stamped VIN looks original and not ground on.

Cool engine.

400guy: If you've got the PHS documents for this car, you can also verify the engine unit number on the car "Billing History" form.
It should match 0585920 (or at least the last 4 digits of that number)
It might show: WS5920

I have the PHS invoice, but I do not see a "billing History" form

EUN won't be on any form from PHS on any car after 1968 unless you have GM of Canada documentation.

Just to sum this up........(if I'm reading the codes right?)

We have a 1970 400? block cast on May 19/70 in a 70 T/A vin (228870N122912) that was built in the first week of June 1970 with a block code stamp WS & partial vin of 29N122912?

Is your car a survivor,restored OR basket case?

Is displacement (400) cast above pan rail behind fuel pump?

Has block cast # below rear of PS cyl.head been tampered with or modified?

The car appears to be original except a re-spray, but in excellant condition

The Block casting # has not been tampered with

I will have to verify the (400) cast tomorrow

[mscicluna007]

their is two other partial VINs you can look for also. One on the Cowl under the Passenger side guard under the heater blower motor. Might be hard to see but will be their.

The next is on your gearbox but it will be hard to see without taking a thousand photos blindly but if your gearbox is out it will be easy.

[2manyT/A'S]

Not wanting to hijack this thread.........,BUT while I have ALL of the "eagle eyes" here...what's your take on THIS block stamp....?

[RamAir]

So...The consensus is a miss stamp from the factory? Everything else on the car is stamped and date coded correct so I have no reason to believe that the engine was re-stamped.

[Baron Von Zeppelin]

If it were me, the next step would be to check the locations where Fremont and Atlanta stamped their VIN's. The normal area (where yours is stamped now) remains clean and fresh for pickings on most Atlanta and Fremont blocks.
-- just saying - its another possibility.

I've seen quite a few (dozens) mistamps/double strikes-
but just have never seen one where a chunk popped out under a couple digits and then had just a couple/few hand stamped singularly.

It seems like they would have just moved over and hit the gangstamp again.
{speculation}
But much quicker for a line worker.

The 9 being in the year model placement "could" have been an error made by someone doing the devils work who wasn't fully up to speed on all details. fwiw

That late in the game - a faktry worker would have been well acquainted with the 0 by then. And mistakes CAN happen, i realize.
Just laying it out there if you want to exhaust all possibilities.
