Is it a 1969 Z/28?

[69Z28-RS]

Thanks, December narrows it down for me.  These December cars are a pain, right when alot of changes happened it appears.
    Probably safe to assume a 4th week of Dec Norwood car would have YH's on it.   Oddly I just did a search and the only thread that pops up on AD wheels is the one we are talking in, lol,  but I'm not computer savy either.

I updated my prior post with another link which might help.

Re your 'December car' being a pain re the changes... OR you could have a LATE '69 car when many of the parts were being changed to '70 model year production..      'running changes' are a fact of life in manufacturing whether it's a '69 Camaro, other car, or whatever...  It adds a lot of fun to our searches for information and parts though..   Right?

Yeah, it's all good

I thank all of you gentlemen for your assistance, it appears that I have YH wheels on the back and FW on the front. I sanded where the original stripe should be between the trunk lid and rear window and do not find evidence of an original stripe. I don't know what I have, maybe a SS Camaro 350?  In any case, someone went to great lengths to make it a Z. I think I will take Williams advice and build a hot rod....any input on a crate motor that would be most desirable in the build?

Did you check behind the rear seat for the X?

[jdv69z]

I've heard wheels were changed from AD to YH as a result of the availability of the 4 wheel disc brake option. When did that option begin? My impression has been around Jan 69, and also that's about the time the wheels changed over. How long would it have taken for a YH wheel with a 17 Dec manufacture date to make it to the assembly line? The assembly plant would also have to be notified so that the broadcast sheet could be revised from AD to YH correct? Any broadcast sheets out there from this time frame?

[jstanley]

I did check behind the seat but I don't see any crayon marks, but if they weren't putting the x code on the cowl tag yet would they write it behind the seat?

[BULLITT65]

I think Jimmy V said his car is a pre X code, and has it behind the seat.

Go ahead and give a little more detail for your application: street/strip, cruising only ,daily driver ? do you want to retain drive line you have in it? Personally I'm a fan of bigger cube small blocks, I ran a 400 in the Z for years ,ported and polished 2.02's, high rise intake, cam card at home, but I can give you the specs later. Stump puller at the bottom end ,screamed at top. 4.88's were to steep for the street. With the 350 trans, 3.73's would have been the better street/strip set up. Block did duty in a race only Chevelle, then I bought it ,now it's in our Anglia ,real mule. Dollar for dollar I think you cant go wrong with a 383 crate...match your converter to the cam. I'm sure many opinions on this.

[janobyte]

Actually for the proper convertor(stall speed) you get with somebody like Transmission Specialties, answer their questions ,and they will build you what you need ,good price ,warranty ,and if you do race it ,you can send it back for inspections (for a fee). Very stout unit. They stand behind their product.

I have personally seen 2 pre X code cars that had the marks behind the rear seat. One car was in the 9N546xxx vicinity.

I don't know if this car would have that, since it is so early.

Yes, Jerry M. found it on my brothers early pre X coded Z when he had it inspected a couple years ago. Put a very bright light on and maybe a use little soapy wet rag to lightly clean the area. If that area has never been blasted, repainted or replaced it could be there. I watched Jerry do it. You have to look very hard on his car to see it but it is there.

Edit: Bryon could be right, I think my brothers car is a Oct. build if I remember correctly.

My Van Nuys 1969 Z with an 01C build date has YH identifying the wheels on the chassis broadcast sheet. 

[HOT3O2]

The last "AD" rims were dated Oct. 24 (68). The first "YH" rims were dated around Dec.17 (68).

[firstgenaddict]

Some are written in yellow grease pencil and when combined with the yellow contact cement used to glue the package tray lip down are difficult to make out.

This is from a 10D TT early Norwood build. The X is to the left of the indent and the 7 is to the right... I left all of this intact and as is for any future identification being an early car with no X TT. I felt that was the X tag for the car.



A ss 350 with black trimmed interior would have X5 or X1. Red interior R5 R1 and so on and so forth through out the interior trim colors...

[BULLITT65]

wow, that is wild. I would have missed it altogether until I looked real close at it. Good eyes James
