Both tags have been off the car. Would like to see the block pad with the paint removed. Seller has refused.

Proceed with caution.

Carb is dated same as my 10B 69Z.

 Listing in the past on this car states “ Under the hood is a correct, but non numbers matching 302 with the stamped sequence”.  Must have found it’s orphaned engine in the last ten years.

I'm sure that's what happened...

Great detective work!

[AFONEFE]

Now the seller is saying that this is a non matching numbers car.  By the photos given how can one determine that this is a Z/28 Camaro?  There are no photos of the tail pipe adaptor or where the speedometer cable exits the firewall.

By themselves, the speedo cable and tail pipe adaptor don't mean much. Many LM1s and all 4-speed SS350s have both.

That is the quandary with nom Van Nuys and early Norwood cars. All you need is an SS with its original Muncie trans and you are well on the way to building what could pass for a nom Z/28.

[AFONEFE]

I believe you are correct.  GM built 20,302 Z's and there over 100,000 on the road or in collections.  Can you tell what photo 304 is supposed to show?  Its looks like the back of the intake manifold and the cowl area.  Trying to figure what the yellow paint is from.  Thanks.

One Z item which would be tough to find if not original is the 15 x 7 AD Rally Wheels dated before this car's production date. Early Z item only and one I would be looking for if I was interested in this car.

The steering arms casting numbers can be looked at.  Not many people will bother to swap them on a clone and they are not common replacement wear items.  Bulkhead markings can help, but you have to tear the interior out to see them.
 Casting dates on master cylinders can be checked but not many original ones will have lasted this long so....

While there are LOTS things to check, if the original block numbers are gone and it has no real paperwork.....You CAN find stuff to rule it out, but you will never be 100% sure it is authentic.

 AFONEFE , i think that a yellow wire goes to the coil [page 304]...

[AFONEFE]

OK, he must be mixing new and old photos because photo #249 shows the coil with a blue wire.  Another example is photo #244 showing the valve cover emblem missing and #220 with it installed.  Thanks.
