I agree with Nowhere Man that it is not 100% these are both GM factory stamps. The "o" before the HR is actually a "9".........and this may well be a legitimate Flint engine stamping.
The VIN was stamped with a gang holder at St Louis, and your engine VIN derivative has a noticeable slant to it. The first few numbers look pretty good, but after that things go south. So on this part I give 50/50.
Take it for what it's worth: free advice over the Internet based on a single photo of a painted engine pad.

Done by humans. The line worker was working on a moving assembly line with limited time to get it done. Very few perfect stampings left the factory. Gang stamp held at an angle when struck, deeper on one end then the other. Most people don't even know the things to look for when scrutinizing a stamping. Needs to be paint free, remove without scraping.

By 65 that line worker has stamped engines for 5 years with close to 75k engines under his belt for practice. He made them look better then that

Well i've owned 29 midyear corvettes through the years and seen a lot worse stamps. And when i went to an ncrs meet about 30 years ago i met a guy there that was a top dog on the chain line that ran the assembly line. I ate lunch with him and dale periman ( sp ) *varoom* after a class with noland adams. This guy had been retired since the 70's . He was quite informative. He laughed about the ncrs judges sticking thier fingers on the head of different bolt heads . He said hell that line ha better not quit when he worked there. So when someone didn't order enough bolts for some thing ( no computers back then ) they'd come and raid his nut and bolt crib if the ran out of a certain bolt. And when dale quizzed him about vin stampings this guy said hey when a guy that stamped took a day off they might put anyone on the stamps... The line never stopped or someone could loose there jobs. Question? Anyone here old enough to recall what dale ( varoom ) had stamped on his 400 small block 62 driver? It might be in an old driveline.
I KNOW THIS IS A REAL FACTORY STAMP BUT WAS WONDERING WHY THEY WOULD HAVE USED A SMALL o BEFORE THE HR?
F0419HR is April 19, 1965 the day the motor was assembled. ''CLEAN'' the PAD with ''PAINT REMOVER'' not scratching force. The numbers will appear with original Broach marks.The ''HR'' is 327/300hp with POWERGLIDE and AIR CONDITIONING. Nice car
I'll use some thinner and remove the paint. I've had this engine sitting on my shelf for 35 years. It was rebuilt and repainted a long time ago . Don't know where the car went . I bought it from a machine shop in Pa. Just getting engines out to sell and saw this. I doubt wether anyone was trying to phony up a 65 automatic with ac engine car, maybe it is out there somewhere I have no idea.
My 2 cents,
1) The op says he knows this stamp is real factory stamp, but ask why small "o"
2) NM always knee jerks to fake stamp
I have been around a few one or two owner cars with there original engines and been shown by very knowledgeable people. take what I say how you will. You know what they say about opinions. While no one would fake a low horse stamp like this. But many machine shops deck blocks for what ever reason and just stamp them with what they took off the best they could
Ah, the old stamp pad brouhaha...
I worked on a Navy aircraft production line (in the 70s) and also did some hand stamping of components....Woodie is correct, you did what you had to do to keep production flowing.....I would think the automobile environment was the same. Gang stamping metal parts took some experience to get good at. Alignment, sufficient whack with a hammer, consistency across the characters - as much art as science and we had rotating Christmas-tree bins of fasteners to assemble parts. When they got refilled the new stuff might not look much like the old stuff (lowest bidder and all that).
Its easy to look back from the context of our CAD/CAM / laser-guided / 3-D printer world and judge what folks were doing a half century ago, by hand, with equipment that got employed to the point it was nearly useless...
On the VIN stamp the second part - 6656 - sure looks different than the first part - 511.......

Its not just the depth and angle of the indentation. The last 4 digits look to be a different/smaller font size than the first 3 .
Is that “typical of factory production”?
