How can the second and third digits be double stamped but not the rest of the digits?

Good old 70’s quality control

Definitely done by hand with little care about keeping it nice or straight

The "V" appears that it may be a double tap too, and looks like it's lower than the "22HW" and aligned more with the faint or shadow "03"? How could it happen, I don't know for sure but maybe it wasn't hit hard enough initially to leave a full impression and the person doing it had to go back and strike it again? With the heavy pitting on the pad's surface and the lack of broach marks, it's going to be real hard to determine if it's a real or retamped pad.

What does the VIN derivative look like, is it factory typical? It would probably help to see the VIN stamp and know the casting date of the block and the build date of the car, to make a better guess about the originality of the engine stamp.

But the stamping on rear ends was done by hand, so they were always somewhat messed up looking. The stamp on the engine's pad was done using a gang holder so the digits are usually fairly uniform in their positioning.

The HW stamp was only used for 2 engines: '65 Corvette (327/350 A/C, TI, 4-spd) and the '69 Corvette (350/350 4-speed) Since the engine has the V character for Flint rather than the F character we know it's supposed to represent an engine after '66. "Represent" because that pad's background is seriously textured and not showing factory broaching or circular fly-cutting from decking but the stamps are deep and crisp. I find it a bit suspicious.

What other options does the car have?
What are the dates on the block, heads, intake, and exhaust manifolds?
