Thanks for the block offer, but I'm sticking with my misstamp block. It was assembled 9 days before the body (StL) so it seams dead on. The trans case vin matches the car (last two not flip flopped). Thanks for all the insight. I have a few other cars in my collection with human error, none with this though. I love the car and have no plans of ever letting it go or making any changes to it other than the current freshening up its receiving. I've just always been curious about the block stamping. Thanks for all help provided.

This quote, which is correct in its import, points up the stupidity of the NCRS judging system. Everyone knows that mistakes were made in the factory, that parts were substituted to keep the line running, etc.
Why should an owner have to replace a part that all logic indicates was original to a car just to conform to an arbitrary standard set by an enthusiasts' group. Instead of forcing adherence to its standards, NCRS should celebrate those production line "errors" that make a car's history so interesting by establishing a system whereby anomalies are accepted upon a reasonable showing of fact concerning the part or number in question.

As I recall, engine and trans were stamped at the same time, and with the same gang holder.
I used to own a 73 base motor car that had the last digit overstamped (originally stamped with an 8, then overstamped with a 7. However, both the engine and the trans had the very same overstamp. Engine and trans were originally gang stamped with an 8 in the last position, then both were gang stamped again with a 7 in the last position. The car's VIN ended in a 7.
My point being, I believe that the engine and trans were stamped at the same time, by the same person, and the same position on the assembly line, and using the same gang holder.
In your situation, the anomaly would have been that the engine was stamped with the last two digits reversed, then the characters in the gang holder were switched to the correct position, and the trans was stamped. What puzzles me is why the engine would not have been stamped again with the correct VIN afterwards.
Still, it sounds like a great car, and I applaud your decision to leave it as is. It would still be interesting to locate the car with the other VIN and see what that situation is.
Good luck with your car.

I'd still like to see some nice pics of the pad and the trans. stamping. If the only difference are the positions of the two last digits...........

Actually, two different VIN gang stamp holders were used to stamp engines and transmission for most of ’65 through ’67. The engine gang stamp began with a digit for the year, followed by six digits for the VIN. The transmission gang stamp began with a digit for the year, the letter S for St. Louis, followed by six digits for the VIN.

In the case under discussion, the transposition of the last two digits is a most understandable error, particularly if the owner can demonstrate a clear history for the last 40 or so years showing that any restamping would have had to have been done before then, i.e., at a time when numbers were not considered important and there would not have been any motive to lie.

Ara -- Yes, the OP was referring to a '66, and the thought of checking the trans stamp was raised in thread #12; my post # 28 was to point out that, starting in '65 they still used 7 character holders for the trans, but the year prefix was replaced by "S"; then in 1966 and 67, with the trans holder changed to hold 8 characters, these 3 years probably did NOT use the same as that used on the engine pad.
Nevertheless, if the OP could check the trans, that would help this discussion.
P.S. W.Guy: your VIN reference to end-of-'65 production being #23562 is a bit out of date. Chevrolet has confirmed that 2 more Corvettes were produced in August, so the last is #23564 (the convertible on the left in my avatar).
