It's shown in the first post of that "L72 Thread' I mentioned. C2 1966 L72 count - CorvetteForum - Chevrolet Corvette Forum Discussion
There's a '3' also shown on Post #81 and Post #85 but...those threes are in the VIN, not the Date Code Stamping.

The 3 needs to be in the engine stamp and not the VIN. The reason being that the two stamps were done at two different manufacturing facilities at different times with different tooling; the stamps' characteristics are not comparable. The 3 also needs to be in that place value position on that date, though the engine code can be different. This lends high probability that the same gang holder and stamps were used so that character shape and characteristics can be compared.
In other words, find another Tonawanda block assembled on Nov. 3rd, 1966 and you will have definitive proof one way or the other as to the 3's shape.

Actually my presumption is that the second block is not a re-stamp. But yes, you need more examples of 11/3/66 stamps to see which shape 3 was used on that date. If two flat-topped threes are found, then the round is likely a re-stamp; if two round top threes are found then this one is likely true. But then it also becomes a matter of comparing the T11 characters too.

I do NOT have another 1966 Tonawanda BB assembly stamp for T1103IP, but went thru many 66 Big Block ONLY images looking for the '3' character.
All together, I found eighty-two (82) instances of the '3s' with the FLAT TOP... while there wasn't a singular '3' with the ROUND TOP, on an original date stamp.
Nothing conclusive, as each day, the assembly date stamp is unique... and they likely differ, even between IL and IP engines.

It’s a fraction of that if he can’t affirm the pad though, can’t find the paperwork but I think it’s around $50 to $100.

But at the end of the day, you are still going to be second guessing.
So when you sell it, are you going to say matching numbers, like the guy you bought it from? But if you have no documentation or certification, can you honestly say that?
I guess it’s on the buyer to do the due diligence.

I do not have a lot of '66 stamps in my photo collection. I do have a few hundred '67 stamps. I know its kind of an apples and oranges situation since its not the same model year however, here is a sampling from early, mid, and late '67 production.

I'm not a stamp pad expert by any means, and I cannot comment on the 3. But, I do notice in the OP's image, the top and bottom horizontal bars in the date code's "I" (for the number 1) have longer bars than every other example in this thread. In fact, every other example posted here appears to be consistent.
