Default Forged Stamp

So I called a listing for a 1969 350/350 and the owner sent me a picture of the engine block stamp. Says its date coded correct but is after the build date, and claims numbers matching, however there is only a partial vin on the stamp and the rest is just wrong. The broaching is gone. See Pic!

VIN: 973409 K11 24 CN

Obviously it's not correct but has anyone seen this before?

Looks like a McKinnon Industries(St Therese) stamp. They have crazy suffix codes, and I don't have that book. I suspect maybe an Impala.

Don't understand what you mean by "Says its date coded correct but is after the build date" ... ?? (What is correct and what build date?)

What is the other information for this car ... ?
full VIN ?
Casting number of block?
casting date of block?
full picture of the pad?

Whatever it is, its not an original 1969 stamp for a corvette.
If you want a original born with engine in your corvette, pass on this one.

Ill check it out.

It looks to me like they tried to make a matching numbers car without doing any research whereupon we have this result. I'm not going to dox the guy or the car but it's certainly interesting.

Do not have a dog in the hunt at all and others know a lot more than I, but I thought a long time ago, engine builders might have restamped pads after a rebuild or replacement to keep the "theft identification" feature. Assuming that may have been useful.

And second, awhile back I saw somewhere on the internet that you can pay some $1000+, (maybe more, forgot) to get a jamb up, "Mona Lisa" pad stamp of any numbers of your choosing.

So, I would suggest that anybody be very, very through in an inspection before paying a premium for "numbers matching" Corvette.

If you can convince the seller that it is not numbers matching and get a NOM price and you really like the Corvette, then that might be an option.
