1967 Corvette Stampings - Opinions
 

Looking at buying a 1967 L-71 Corvette and would appreciate input on the transmission and engine pad stamps. These are the only photos I have available at this time. The trim tag shows a December 14, 1966 assembly date. I appreciate the photos are not ideal and the pad/stamp examination will require more time and attention.

You're looking at buying one of the most forged vehicles out there, the 1967 435 horse Corvette. Be very, very cautious. Does this Corvette have any paperwork?
Did I mention to be very, very cautious?

LOL. Tim the car was originally sold in Canada and has Canadian paperwork issued by GM Canada Vintage Vehicle Services so I'm not concerned so much about how the car left the factory, rather more about its stamps.

For reference, here is the pad from my 400hp car that is a known original motor. My Dad bought this car in 1975..........

These pics are from about 10 years ago. If you like, I can send some updated ones.

Hope this helps answer a few questions.

Photos are insufficient to make a judgement. PM me for further details if needed.

Thanks Dan, I will be viewing the car on the weekend and plan to take some hi-res photos.

Canadian docs show options in '67? Can you post a picture of them?

Lloyd, you should get Al Grenning (CCAS) to authenticate the pad, he is the leading authority on Corvette engine pads .

I believe Al would reserve judgement until he can look at a more detailed picture.

Yes I 100% agree, Al requires certain picture pixels and size.

Lots of very knowledgeable people on this site, but I think Grenning documentation authenticating the pad would go a long way to the cars value, lots of fakes out there as noted.

BTW- Tim, think I met you in Calgary a few yrs ago,

I remember the Calgary trip well and I remember when we met. That was a wonderful trip.

Very wise move

Strongly believe that is a restamp. Need better photos to determine.

Thanks for all the input, I was fortunate that a member shared with me a good photo of same date stamping. I now have what I need for reference.

Yes they do. If I purchase the car I will post the GM Canada doc. As the document is not (yet) mine to post it will have to wait.

Al will only authenticate a cylinder case for the owner of the car. He does not conduct pre purchase inspections

Al isn't inexpensive either & you pay the same $$ if he says thumbs up or thumbs down. It's worth it if he says thumbs up though!

Canuck L71
 

I believe I have the most extensive data in existence on 1967 Canadian delivered L71s and have 106112 in my files, including engine history, etc. It was delivered by Gorries Downtown Chev-Olds in Toronto.

That’s not exactly true. Yes Al is costly but he’s the expert. In terms of cost - he only keeps your money if he affirms the component. A service fee of $75 is assessed if a component is deemed OEM or not but the affirmation check is returned if non OEM is found.

Dan

That’s old school fair!

Is that NCRS terminology for a block? Never heard that before.

When I spoke to Al about affirming my block assembly stamp, he didn't mention returning funds if not affirmed. Seems like a pretty good risk to take - essentially a $75.00 downside risk for the potential of the certification of "born with" components. He told me that he only did Corvettes at that time though - recommended JM for Camaros.

The pad looks different than the one on the documented Canadian sold L71 I looked at Sunday - which the owner has had since the mid 80's and does have the original block... although due to 2 thrown rods, the block had significant reconstruction at a NASCAR engine shop during the 90's.
By the way per the Canadian paper this L71 was factory equipped with bolt ons, side pipes, and head rests - Goodwood over Green Roadster...
