One reason I posted this car is because it is a very rare and beautiful car that caught my eye. The other reason I posted it is because it is up for sale on an open public site for a lot of money. I truly feel that this site is the most fair and informative Camaro site anywhere period!! As much as i would love to own a car like this (and i have owned a Z/11 in years past) I am not in the market at this time. The problem is in today's classic car world there are so many fake, restamps and clones that have helped to ruin and hurt the value of our beloved hobby. That keeps experts on here and other sites constantly keeping data and records so that when these cars come and go for sale over the years we have some help to look back on in case one of us are in the market. Since I have been on this site I have been shocked to see so much dishonesty and forgery with these classic Camaro's.
Now with that said I am in NO WAY saying that I believe this beautiful rare car falls into that category. To me the only things that looked worth questioning is the clear, crisp VIN stamp on the block that are usually very hard to read. Also, unless it was a factory mistamp shouldn't the VIN stamp have been 19N6xxxxx and not 11N? Factory misstamp?? James brings up a good point, a simple check of the trans stamp could help to answer that. Also, the very, very early casting dates on the block, exhaust manifolds, 3:55 posi rear etc. raised a question in my mind. Even though they seem way to early I guess anything is possible.
I am in no way questioning you or the current owner but from 1969 to 2006 is a long time and we definitely know the engine was out and things were done through those years. Again a clear shot of the transmission VIN could clear that up easily as they should match the block exactly. All the best to your friend with his sale and hopefully our discussion on here will help to validate this rare and beautiful car and help him to sell for it for top money. That is my hope!
