That stamping looks okay to me from here although the original broach marks may have been inadvertently removed by improper cleaning of the stamp pad. Chevy engine plant at Flint used capital letter I's as the number 1 in block stampings - don't ask me why.

Nothing about this says re-stamp to me: character use, shape, spacing, and baseline alignment all looks great.
The timeline from engine assembly to VIN is a tad longer than "normal" at 4 weeks (12/15/65 to ~1/12/66) but maybe with the holidays or other delays (rail slowdowns, weather, etc) isn't a red flag for anything. Most timelines are a couple-three weeks.

flint was producing about 300 engines an HOUR I doubt they changed the cutting heads often. If you really want to have peace of mind find known real blocks assembled the same day as yours and compare. Or pay Al Greening his fee

that pad was painted once by observing the paint in the letters.
it has a aged patina
it has a aged edge and not a sharp pad.
it looks decades old .. probably more than a couple.
but the paint on the numbers may mean a rebuild and paint.. unless previous owners painted the pad and then removed the paint on the pad and let it patina out.. or was already patina'ed

Even if assembly date is the same as another block, you won't know that the blocks were broached on the same date. Additionally, I don't know how many block broach lines Flint had going, so a comparison also may not be definitive without knowing they went through the same machine. I don't think there's any way to determine either thing.

yes, blocks were cast, broached, machined, then went into a room to sit there to be built.. did the factory have more than 1 room? more than 1 broacher? was policy absolutely first in and first out, or first in last out in that room. the build dates of the engine can be weeks or months apart with 2 cars ( vin x and vin x+1) in line at the car assembly plant..
and... when a rebuild shop does a shot peen/cleaning of the block to be rebuilt, the broach marks are now gone...even without decking the block.. and the stamp is untouched.
all sorts of things can happen and cause one to suspect the stamp pad.. doesn't mean it is not the original engine.
