How rare 69Z options

[KurtS]

I have some of the old Camaro secret facing papers.

What are these secret papers you have? Can you expand on that?

Probably the AMA and SCCA paperwork which was submitted to those organizations. The SCCA used that info
to determine what parts were production parts that could be used in competition.

X code information found above....started mid December 1968.

I know what my car was and is. It has X33 on the tag. Sell date was in Sept 68.
Serial numbers all match.
Canadian cars are different. Canadian Pontiacs that races could use Chev engines. A good friend's brother had an original numbers matching 66 SS 427 Chevelle.

As for the papers and specs. I have somewhere a copy of the specs submitted to SCCA for homologation. A long time Chev parts manager had saved everything, he let me and another friend look at them and copy some. My friend had saved everything a 68 Z that had spent its life on the track before being converted back to "street". I went over the car before he bought it.

If you believe that is the case, post a pic of the Fisher Body tag here or email it to me and I will post it. This would be the first instance EVER of a tag that early have the X33 Z28 coding on it.

And I believe you are incorrect on the 1966 Chevelle 427. I follow Chevelles pretty closely too.
