Opinions on this stamping?

That isn't even close to the factory font or impression. And the factory did not stamp the number on two lines.
Compare to these known factory stamps.
As compared to this:

Agreed. Never seen a factory stamp look like that. I've seen two lines on SR blocks but obviously no vin number on an SR block. Depth, spacing, two lines, and font are all wrong. This is from a '71 Bittersweet W30 on ebay right now.

Also note the relative angles of the characters - I believe that the original stamp was made from a single holder that was loaded with the correct number, then stamped on the block, transmission, and perhaps a few other places, depending on year - the original characters may have had slight misalignment top-to-bottom, but rotationally they were all straight.
These characters were individually stamped, and each is on a slightly different axis.
It doesn't even look like the "re-stamper" tried.

I agree with Dave that this is likely a dealer replacement. The dealership was SUPPOSED to transfer the original VIN derivative to the new block when a replacement was installed. This often did not happen, and there was no direction (nor likely the ability) to replicate the factory font or format. Only the transfer of the characters mattered for legal purposes. Frankly, having the restamped VIN derivative be so different from factory is an advantage in my opinion, as it makes it easy to prove the engine is not original. In any event, the dealership didn't care about such things then, just compliance with corporate directives and federal law.

That would seem to be the most likely situation in which the re-stamper would not even care what the stamped number looks like.
It's actually interesting to see a replacement engine that appears to have been stamped according to the guidelines, because so many of them appear not to have been.

Carb looks like a service replacement carb due to the date code, and I was thinking the 7041253 was the regular 442 manual transmission application but not W30. It has a newer alternator, not an open faced one. The spoiler also has two studs holding it on, I believe factory spoilers had three studs each side. It looks like a really nice car and the build sheet is a super find. But the ad calls it a survivor and says the bolt on's are all original. Then it goes on to say they've located the original heads. So... I have more reservations than just the vin stamped in the block. John
And... I believe the radiator tag is the same one I have on a 4 row radiator. But the top plate on this car isn't a 4 row top plate. It's the non-shroud 2-3 row top plate. The exhaust crossover on the intake look rusty, so its an iron intake.

Possibly formerly a external regulator car? 3 holes in firewall center behind air cleaner, look like where a regulator may have been bolted on. Drivers side trunk dosent fit well, maybe the light but the paint seems to not match in that area as well.
But its a beautiful car, one of my favorite colors on one.

This car reminds me of the 71 Bittersweet that used to be on this site few years ago. Here is the old post:

This is the nicest '71 W-30 I've seen at a national meet. Well documented with a window sticker. It did not have regulator holes in the firewall either.
