Default 71 LT1 Authenticity

Can any knowledgable parties comment on the authenticity of the motor for this 71 LT1?

Based on what I've read regarding engine pad identification this one doesn't quite add up. I don't understand the K08 prefix on the VIN derivative engine pad.

That appears to be a really poorly done re-stamp of a motor

That's one of the worst restamps I've ever seen on this website. Probably a rebuilder's stamp, not intended to fool anybody.

That's why I posted. I am new to C3's and I guess I still have a lot to learn. I was on the verge of closing on this 71 but now I will pass. Unfortunately, I'm out a moderate deposit but it could have been much worse. Imagine how I would have felt after buying the car

Thanks for the feedback. If anyone has a different opinion please chime in.

I'm finding it really difficult to find a clean authentic 70 - 72 LT1 at a reasonable price. My idea of a reasonable price is 20k - 35k. I wish I had jumped on (one of) the pair of LT1s that recently sold but I was on the fence and not wild about traveling out of state (again) to inspect a vehicle.

With all due respect, if you're considering buying a high end C3 and having an original engine etc. is worth paying a premium for, don't even think of trying to inspect it yourself or via photos over the internet. Hire a professional.

Do a search on this website and you'll find all sorts of tragic tales of people not doing due diligence prior to purchase. In this case, did the seller advertise the car as having the original engine or was at least 'matching numbers' If so, why can't you get your deposit back?

Sounds like good advice. Do you know any in the US that can travel to any of the lower 48 to inspect a vehicle? And what would that cost? This car is in Houston, TX and I recently posted on the C3 FS forum asking for help to inspect the car. I offered to pay and there were no replies. I have also tried emailing a TX NCRS member for leads on this type of help and got no response.

Hi guys, could one of you, Mike Ward or Solid LT1, please give a bit of explaining of what is wrong and why the stamp is "poor". Not questioning you at all b/c you both always have great advice and exhibit a wealth of knowledge, I am just simply wanting to learn more on how to tell what's right and what is wrong. Is it b/c of the unevenness of the numbers and the varying depth of each stamp or what? This could also help the OP on an argument as to why he should get a deposit back. Misrepresentation or false claim of original engine and all.

thanks for the info.

I would suggest going directly to the NCRS site and contacting them there. Be prepared to pay $300-500 depending on travel distance.

Here's an example of a real pad (photo shamelessly borrowed from John Hinckley )

The engine stamp is not original, and is very poorly done. The engine could still be original and have had the stamp milled off by an idiot engine builder who tried to correct his error...but you will never be able to prove that it is an 'original' engine.

However,if you are not going to enter this car for NCRS or Bloomington judging but you still like the car, just offer a lower [and more appropriate] dollar amount for it {assuming a non-original car}. No one else is going to give that guy a premium for that car....the engine stamp is just too bogus. The trim tag has been removed and re-attached, also; so you can't know that it was the correct tag for that car.

If you have checked for condition of frame and birdcage (no or little rust) and the paint, interior, and mechanicals are all in good working order, it should still be considered--at a lower value.

I'm not interested in NCRS competition myself but I do want a C3 that is in excellent more or less original condition. The frame and birdcage looked clean. The paint was almost perfect and the freshly rebuilt motor ran great. The car had been body on restored in the last couple of years. It drove nice, straight and tight. We had agreed on 28k but given the engine pad what would you consider a reasonable price? 20k or less? Regardless, I will pass on this car.

Since you've given few details of the car other than year and possible LT1 motor, impossible to say..........

Hi WK,
It seems like you've asked about the pad just in time.
There are LOTS of things to look at to determine if an LT-! is"real" or not.
The stamped information is what comes to mind first, but the list is LONG.
If you're interested in having someone look at a car with you or for you, if you post the location you'll get some suggestions for knowledgeable people in that area.
Good Luck!
Regards,
Alan

PS: When I looked at the pad you posted I first noticed how heavily it's painted. Along with the stamped information it's good to be able to see the pad surface.

PS: This STILL could be a LT-!, and the original engine for the car it's in, but lots of work needs to be done to come to a conclusion about that.

Hi WK,
The fellow who put a great list together of what to look for on LT-! cars is David Mayhew. I looked for the post but couldn't find it. Perhaps if you PM him (dmayhew) he can point you in the right direction.
Another source of information is the NCRS '70-72 Technical Information Manual and Judging Guide'. Even if having a car judged ISN'T in your future, you'll learn a whole lot about LT-! cars.
Good Luck!
Regards,
Alan
