71 LT1 Stamp Pad

[Erv M.]

This car is being auction in Dallas. What do you think of the stamp?

Re: 71 LT1 Stamp Pad

I spy with my little eye- a possible grind out and restamp of the last two characters of the engine machine code stamp

Here's my spin Erv, stamping of your block specifically build date appears untypical (as compared to others). A little sloppy and stamped deep into the block with virtually no broach marks on the pad. I've attached the pad to my '72 LT-1. Noticably different.

Not my car, it is one advertised for an auction in the near future. Last Mecum auction a 70 or 71 LT1 went for $23,000. Had to be a reason.

Probably real.

Mike,

Any higher resolutions photos of your pad?

What's on your mind Pat?

Re: 71 LT1 Stamp Pad

Let us keep our eyes on the prize, well not the prize but the first stamp pad. I am somewhat interested in the car and wanted to receive some feedback.

Re: 71 LT1 Stamp Pad

Since I've had the experience of buying a fake one I'll bite.

The VO is VO in one and V "squared o" in the other.

How can the both be correct?


Did you look at the last three and compare it to the known engine codes and options for that car and THAT year?

Then as Michael has indicated - it does not look neat and consistent with being punched in with the holder that was used to get the crisp stamping like the other one shown. More like, one at a time...


What else is wrong with the car, did you pull a valve cover? I know... at an auction all you can do is get excited and just buy it and cry later.

Ron,
At the end of each day the stamp holder may have been dumped of dies and refilled with the next days date. Thus the shape of each character may be consistent for that day and for a given suffix character set only.

I post this only to explain "How this can be" and not to make any comment on this or any other engine pad.

Re: 71 LT1 Stamp Pad

And in doing so they became inconsistent up down - not likely. Over lay these in photoshop and the variation is obvious. The impact angle is not consistent letter to letter.

This weekend I'll have to pull out the 70-72 engine code tree chart we made back then in discussion with the release engineer.

I think it's OK based on this one photo. Better resolution photos would be nice, and seeing it in person would be best.

Note how each of the characters in the VIN stamp are evenly spaced left-to-right based on center-to-center. Based on how the characters were made and in the holder that's the way they were from the factory.

Same thing with the first 2/3 of the date and manufacture code stamp.

Now go see it in person at the auction and see if it looks OK to your eyes.

There were three distinct zeros used in that era, the square, oval, and round. I have seen at least two of them used in the same machine code, and think I have seen one with all three. Maybe our resident "stamp expert" will chime in on this discussion as he owns an LT-1

Re: 71 LT1 Stamp Pad

"CGZ" is correct for 1971 LT1 MT (as per little black book).



My 2 cents...
the stamp for the VIN looks very correct (font etc..)
the stamp for the engine, maybe a little suspect of "fakery"

However -
if there is other sufficient documentation for the car (POP/real window sticker, owner purchase order . etc...) to truely identify the car is a real LT1 car - I personally would not have an issue buying the car if the auction price is fair.

If all the other hard to find parts are date/# correct and the car is a nice car, it will still judge well even though the stamp pad is questionable.

A "top flight" and/or PV is still obtainable - but it would be pretty hard to get 97% or higher, or a Duntov.

For what its worth ...

Re: 71 LT1 Stamp Pad

Here's one from an unrestored 70. Pretty ugly but believed to be original.
