Does engine stamp look legit for a 63fi?

The configuration looks right but the heavily pitted pad surface makes it impossible to make any real determination from just the stamping. I would assume it's an "870" block? Is the block's casting date close to the assembly date, (late September to early October 62)? VIN 3177 was built November 10, 1962, it would be helpful to find some other 63's built the same day to compare this pad too.

If it was a 250 or 300 I would say it was fine, but as a fuelie I would never assume it's real until it can be proven further. About 15 years ago I had someone bring me a 63 fuelie to do an inspection on after(!) they'd already bought it. The stamping looked good, but the pad was rough. A quick look at the casting date revealed a 1967 dated "657" block, and it had a 64 fuel unit with a 65 distributor. The owner got pissed at me saying he'd bought it from a friend and had known the car for 30 years, and there was just no way anybody ever changed anything. He told me I didn't know what I was looking at and wouldn't pay for the inspection but obviously he had some doubts about the car, or why else would he have wanted to have it inspected?

I figured out what car that is....I think the tags are in question as well. Also, it has a repro S-tube which will run you about $5K to correct.

Are the arrows pointing to just a shadow or is it a step-down from the head surface to the stamp surface? If a step-down, then it's definitely been altered. A St. Louis or Flint grind-out wouldn't have affected both stamps, and they were nowhere near as neat and uniform as this appears.

To me, the stamp looks too good and the pad is questionable. I have doubts it is authentic.

I am also a doubter............... There are a few things that just don't appear to be GM factory marks.

The threes in the VIN stamp are the wrong shape, also spacing is questionable.

Almost appears as if the pad was pitted before it was stamped.

Front of hood and head light buckets out of adjustment AND NCRS states no hood wedges until approximate VIN 6500 (Jan '63) and this car built (Nov '62) currently has 2 hood wedges indicating front damage repairs. IMHO too many red flags for that kind of money. begee22

i dunno... decked and salt aged would still have a sharper edge, those bumps from the arrows pic are funky and is questionable.
if really aged by mother nature, then its decades old. and nicely done.
someone else comment on the font and spacing..
and confirm all the other dates. never even look at a stamp before you confirm casting code, casting date and assembly date.
