Man, I hate it when that happens. And I still wish a notice box would pop-up when someone wants to respond to a post that is over 2 years old...

Default LT-1 blue door tag.

The original blue tag info prior to the 1972 model year was stamped with running it over the protectoplate.
Can you see anything else on the tag? It should also have tranny code dating.
Can't find any other numbers on the tag. I do have the original engine in pieces thou and out of the car. The block has been decked so no numbers available. Vette now has a built 383 stocker. Thanks for the thread.

Back to the blue door tag I don't see any other numbers on it. I do have the Lt-1 motor although it's apart but all goodies are there numbers and dates match but block has been decked no numbers available. Right now the vette has a 383 strocker.

Check at the very lower left. You could see only the tops of a few letters/numbers.

1971 LT-1. Can't see how the blue sticker can be definitive proof of an original LT-1 ?

Codes on mine listed below:

Your blue sticker is not definitive proof. However, some stickers when the POP was stamped into them also left behind the engine stamp portion from the original POP. Definitive proof usually comes with the whole package and not just one single thing.

Hi,
Often, if given the chance, the car will tell it's own story.
Regards,
Alan

Here's how/why the broadcast code sometimes ended up on the Certification label.
