Re: Help with this engine pad authenticity
I think it's a question of tolerances and precision. If one were to create a gang holder with 7 numbers, what are the odds that all 7 individuals stamps come into contact with the surface to be stamped at the same time. Absent micron-level tolerances, the odds are zero. In the case of the stamp in question, one of the 7s was obviously most proud, followed by the 1 as 2nd most proud.

This is a late 67 300 HP. Other than a couple of items I know weren't supposed to be on the car when I got it, everything else is original or an OEM part. Even the carpets all had their original tags when I replaced them. Flite judged in 89' and 91'.

Re: Help with this engine pad authenticity
Seeing the double strikes, bounce and ghost characters remind me of some of the junk stamps we put out from the Fremont Plant back in the day. Basically, if you could read a number, it was OK. I contributed the Fremont stamp issues to line speed - ours was 47 and hour. It wasn't as easy as you might think to stamp a moving engine, and the operator had other tasks in addition to stamping. When the regular stamp operator was absent, it was a nightmare.
I always thought Corvette engine stamps were pristine in comparison and the examples here don't surprise me. I agree that the broach marks and pad condition should be the determining factors in some of these cases.- Top

Mike, I totally agree with your last line, Who would have ever thought we would be using a magnifying glass and scrutinizing the engine pads on any car 50-60 years later.New England chapter member, 63 Convert. 327/340- Chapter/Regional/national Top Flight, 72 coupe- chapter and regional Top Flight.- Top

See response #11 above. The tool lands obliquely on the pad and only the first and possibly the second characters make an impression.- Top

Re: Help with this engine pad authenticity
We have discussed this before. The light stamps parcel or whole are caused when the gang stamp was set on the pad & sometimes hit lightly with the hammer to get it flat against the pad Since cast iron is not malleable there is some bounce back so when it is hit for real it usually moves a bit. The faint letters / #'S are there before the second deep ones. I have stamped a lot of cast iron & it's not easy especially with stamps that are used & not sharp. I believe that the stamps were changed often & all this crap of a stamp not looking exactly like close other SN'S may mean nothing.65 350 TI CONV 67 J56 435 CONV,67,390/AIR CONV,70 454/air CONV,

Re: Help with this engine pad authenticity
Thanks to all for your insight, I started this discussion for two reasons. First for a little more knowledge which I have obtained and I apologize for those who feel this is a repeat some of us are not as knowledgable and have not been in this hobby forever. Secondly cause I was really interested in buying the car, but it was pulled off eBay earlier so someone bought it before I was ready to pull the trigger.
I do appreciate the excellent education and pictures, and thanks for those already in the know for your patience.
