The IA2 is an aftermarket block based on one originally created by Indian Adventures;

Value depends, Pontiac reused engine codes many times over; Typically value of blocks (and parts) is driven by the cars that they are correct for; '70 Trans Am's and '70 Judges are probably what are really driving up values of '70 Pontiac YZ & WS blocks, as well as #12 heads, and '0270 & '0273 carburetors.

In fact when I look at my VIN stamp, the last 3 numbers look different than the rest of the stamp. Much less deep and distinct. I know that these stamped numbers don't always look uniform but it did get me wondering. Of course, the only reason to restamp would be to make it match, which it doesn't so that doesn't really make sense. Does anyone know when they stamp the VIN on the block? Is it done right after the block is made or just prior to assembly or just prior to installation in the car? Would they do a partial stamp at some earlier phase and then stamp the last three digits just before it goes in the car?

Chevys are easy restamp because the numbers are on the deck. Pontiac not as easy without detection

Multiple ways of detecting also. At least 3 maybe 4 ways to spot a restamped block and they are all VERY easy to tell

Engines were built at Pontiac engine plant to a spec, that is WS, YE etc. A ‘71 YE is a 455 HO automatic, when built it could go to an F-car or an A-car. Loaded on to a shipping rack with 5 other YEs and then onto a rail car with a dozen other engine racks. Next stop final assembly. Racks get unloaded. Engines get pulled off as needed for build. First stop is the engine dress line where accessory drive, air cleaner and other items are installed (look at an assembly manual to see what was put on at final). During engine dress a manifest is used and the build is determined so it’s clear which car the engine is headed to. It could be VIN stamped here or right prior to load into the chassis. Plants don’t do everything the same, but I’ve seen the process more recently and VINs were stamped seconds before being loaded into the chassis. |

Man are you making an example of a real stamp with a restamp? That's bs man. You guy said it's a partial stamp now it's the whole stamp. Come on stop bull sitting me. I was told it was the last digits of the Vin not the whole Vin. But who cares. I think the guys that figure out all codes have knowledge to restamp one . Mine is stock to my car and I ve been told it's fake. I call bs on this. He should keep his block you greedy guys don't care about him and that's not right. What if he isn't happy with his new engine then what? He is then screwed. Yhats not right. I was even told my stock exhuast manifolds where to close to assembly of car just because he needed them. I know Bill **** from experience and I call bull ****.

I think we really need some sort thread dedicated to 70-73 T/A;s and Formula's...for cars missing engines...and engines missing cars.....

I agree. Needs to ba. Sticky and closed so only vins can be posted and not get detailed. With the internet now we probably could match a lot more cars up with blocks, especially if we had kept better track of ones sold.

with anything done by a human, errors happen;
as is the case of these partial vins added to the engine and transmissions. sometimes they were missed, sometimes mis-stamped, other times not totally legible; on occasion, they are stamped more than once.

For 1970, and I have mentioned this before, MOST birds got a 9 in the partial Vin stamping (s) on the firewall, vs a correct "0". Yup, a 1969 designation.
Not the block, but factory did it..

/\ that's interesting;
is it safe to presume that this was for january (early builds), and maybe febuary (early production) vehicles?

Giles,
Thanks for the explanation. I've often wondered if they stamped the VIN on the block and the trans at the same time. It would make sense to assemble them, then stamp both VIN's right before dropping them into the frame, or right afterward. Quote:

Since they were 2 hanging pneumatic stampers that needed to be reloaded as cars came down the line, I can see why it was probably never corrected, or they did not have extra "zero's" .
