Tonnawanda stamps should all resemble each other regardless of where the final assembly of the car was. They should all track familiar in any 396 or 427 for 1967, also. The three things to look for are assembly stamp, VIN stamp, and broach marks. Two of the three (assembly and broach) will be similar in all Tonnawanda big blocks. As far as VIN stamp for Chevelles, others may want to comment on that portion.

----Just asking the experts, but is the "6" on the Tonawanda stamp on the original posters pic correct? the straight leg sticks out to me........Bill S

That is the correct 6 in the Tonawanda stamp, but would not be correct in the vin. stamp

Lets be cautious as to giving tips to the restampers of the world that will read this thread.. Just saying..

I had no idea they made such a low number of those cars. I was in an L78 display with my black camaro years and years back (I think it was chevy vette fest in Chicago), and there was this perfect condition 67 L78 chevelle in cinnamon metallic with same color interior, pretty sure it was a 4 spd. It was all original, and was such a nice car to look at. I think it traded hands at that show for a really big number. Now I know why. Rare rare rare.

look close at op pics: stamp surface *appears* grained parallel to stamping

Personal opinion after looking at the hi res photo is that the stamp is legit. But I am no expert. But as others have stated previously I would make sure I wasn't missing the forest because of the trees. Or however the sayin' goes.. :hmmm:
