Default Re-stamping Question.

So cars can have "matching numbers" engines and not have the original engine due to re-stamping. Question is...can an engine be re-stamped while still in the car or does it have to be taken out to get a reasonable high quality re-stamp? Thanks in advance.

I lost a $100 bill the other day.

I think I'll just print another one as I have the original serial numbers. I mean - I have the right paper and ink- who's gonna know?
Not to mention all the ones the government is printing up...

First you would have to find original style stamps.

fraud is fraud if you're trying to fool the masses then then the block needs to have the head removed. but to make the broaching marks like new then it's going to take a whole lot more

The engine block would have to be decked to remove the old stamps and that would require removal. If not removed, it could be ground out by hand with a die grinder, however, you could easily tell it was hand ground and the restamp would look horrendous. I'd say a reasonably high quality stamp would require engine removal.

In order to make a good job of it, you would need the engine out and completely apart. The block would then need to be resurfaced and restamped.

Of course, you would need to find someone with a broaching machine (with the skill to know how to use it properly), stamps with the correct fonts/characteristics, and finally, the knowledge of what should be stamped into the pad (I.e., dates, orientation, etc.). That’s the complicated part of the operation.

It’s not as easy as people make it out to be.

Regards,

Stan Falenski

Reason for my question was I saw a car on BAT and it had "Matching Numbers" in the description. I don't want to do it myself, just want to understand how hard it is for someone else to do. Thanks to all for the information.

And if you are talking about the little red corvette look what happened. That auction was a disaster for the seller.

I assume once the story got out the seller was trying to hide under a rock. I also assume that the seller will try to sell it to some uneducated genius with too much money to spare. Ike

There is more than just numbers on a block to determine an original factory stamping. There was a process to stamping motors at the engine plants that have patterns that most people restamping can not replicate. The issue with the 70 Red LT1 had on BAT was that he claimed it was the original motor when it was a clear restamp. If he would have just stated it was a matching numbers motor or that it was a restoration motor he would have been better off.

OR if you are going for maximum NCRS points. Either way this is the guy you want, it won’t be cheap but it will get past the judges.

Asking for a friend-

Wouldn't it be cheaper to print hundred dollar bills- give them to the NCRS judges?

Well printing money is a federal crime. Faking cars could be a crime if the right person catches you

Even though engines limited has the broaching machine, it take a lot more to accurately stamp an engine. I have seem some of their engine pass judging then other times they did not. It depends on the level of judging, the judge and what knowledge/resources they have to asses the fonts and configuration. Same holds true with trim tags on early C3's. I have seen cars that passed judging only to find out later that the trim tag is a fake. This more often happens in NCRS chapter judging vs national judging. In regards to restamping a motor, in some case it could make sense if you have a desirable car like an L88, L89, L71 or LT1 (Have supporting original paperwork) and you want to restore the car back to the way it left the factory. In that scenario if the owner acknowledges that the car has a restamped motor, the judging sheets will have the engine marked as Non OEM and the car can still pass judging. The issue is when you have an owner who restamps a motor (or to something other than the original engine stamp configuration in order to increase the value of the car) and doesn't state that to the next buyer. Then you have a sticky situation like the seller of the 70 LT1on BAT last week.

Yep- cheapens all involved-

Saw a story on a C2- The guy's father had bought the car new- auto small block- had some original paperwork with the VIN.
Did a search- and found it for sale as now a 4 speed and grown into a big block with all the original paperwork.

Caveat emptor
