1967 435hp Engine Stamp Pad - legit or a restamp?

[Mark S.]

Would appreciate your thoughts regarding the 1967 435hp Engine Stamp pad below. Does the surface broaching/stampings appear to be legit or a restamp? Thank you in advance.

looks like a terrible re-stamp to me but I am no expert. Does not resemble mine. I look forward to other comments

Looks like it was done with a belt sander

I'm certainly no expert but this looks terrible. Way too large and the font looks incorrect. Sorry.

That pad was NOT stamped at Tonawanda or St Louis. Probably Bubba's home garage.

nope - it was Bubba's BLIND sister/cousin

I think this was the same guy that stamped the infamous Fonawanda pad.

The stampings appear to have been done with individual stamps for each character. The engine plants NEVER did it that way for each character of complete stampings.

Many thanks to all. It appears to me that the zero's in the Serial Number appear to be too fat. The 7's look a bit off as well. I'll gladly stay away from this one....

I want to take a shot at this - not because I'm an expert (not by a long shot) - but as an exercise. I would appreciate a critique of my analysis by experienced judges.

It's always tough to judge a stamp pad from a picture but there are several peculiarities I see in this picture.

1) I see evidence of what could have been broach marks running along the very top edge just forward of the head for about 1/32"
2) The "T", date code and broadcast code look okay as does the very left side (i.e. outboard) of the pad surface
3) The inboard side of the pad appears to have been resurfaced with an abrasive. The grain runs perpendicular with the crank shaft rather than parallel. There appears to be a ridge that runs close to the edge of the head. It starts about halfway across the pad and gets deeper as it runs inboard.
4) As others have noted the VIN derivative looks to have each character stamped individually and there is a great deal of random variation in the depth of each character. The "1" and final "7" appear to have been struck much deeper than the other characters. I could understand the characters getting deeper as you move consistently from one end to the other but it is hard to imagine how you would get deeper strikes in characters 2 and 7.

This all suggests that the replacement block is an original but the VIN derivative was re-stamped (poorly) to match it to the car. How did I do?

Gentlemen,

Me thinks it's a real stamp done by GM. Loose and chracters that are crooked are the norm for BB Corvettes. You would have to remove the head to know for sure.

Looks like a restamp! What is the castings date code on the block? These IMPALA blocks are making a BIG come back. Broach marks are sanded off.

The bigger question here "Does the engine belong to the car?" IE is a real BB? I know of several BB cars >>> one had no documentation and is the real deal for sure, the other has a whole lot of awards and documentation and is well it is not what "owner" states it is.

I had a discussion today with a knowledgable fellow who told me that the early 60's were stamped individually rather than in a gang holder. It was later in the model year that they were in a gang. True?

I believe 59-60 C1's had their VIN derivatives stamped with individual stamping dies. I forgot just when it ceased. However, I don't think the engine code was ever so-stamped. By the C2 era, both stampings were gang-stamped.
