How rare is my old 69 Z.
Early production, sold Sept 68 in Vancouver BC
Daytona Yellow, X33, deluxe black interior, console, gauges, stainless seat/shoulder belts, wood grain, fold down rear seat, fibre optics light monitoring, narrow 68 rear spoiler(early production),front spoiler, chambered exhaust.
Welcome to the site. Where are you finding the X33 code on your car?
My old car. Norwood build, firewall plate. Before I purchased this car years ago, I did lots of research (I know LOTS about early Z28s). I verified a 68 Z for a friend. Worked at a Chev parts department. The local Camaro club back in the day would ask me about Z28s. I have some of the old Camaro secret facing papers and specs submitted to SCCA that has all the modifications.
It also had the Endura front bumper. I added a cowl setup, 140 cam, crossram, passenger side chrome mirror, frame connectors, good traction bars, was told by someone while street racing that I pulled the front tires hitting second gear. It also had dealer installed hood locks, not the pin type.
Car is long gone to a friend, but the crossram is still in my possession. Not an original, but an Offenhauser, mid 70s Winters sold a lot of the performance molds to Offenhauser.
Your car would NOT have had X33 on the firewall tag originally from the assembly plant.
There is no way to say how rare the car is. Chevrolet did not keep track of option combinations.
U46 is probably your rarest option on the car. 1450 Camaros received that.

What are these secret papers you have? Can you expand on that?
Byron is exactly right. Norwood didn't start putting the X codes on the trim tag until well after September of '68.

Who? :)

Were the Stamped Tags in time with the dreaded Rear Bulkhead chalk marks also?

The rear bulkhead markings started to be used before the X codes. I try to call them crayon markings rather than "chalk" markings because it was a waxy type of yellow stick (or sometimes called grease pencil) that they used. But I don't know exactly when they started.
I believe that same type of crayon was used for firewall markings sometimes found when firewalls are soda blasted.
The crayon marks seem like chalk today. You can almost wipe them off with a swipe of your fingers on my 10A early build '69.
I also have different coding due to special interior color. Assume the paint guy needed to know what color to paint the exposed metal interior areas. Not a lot of data out there about this. We do have other color spec in the code examples. It looks like (color)-3 or (color)-7 for example.

The X was the default. It meant that all the interior metal was to be painted black. B, R, & G for sure exist...maybe more....Joe
DG3 would be dark green interior X33.
"LG-7" is for light green with X-77 trim. :D

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.

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.
