Crossram, was there ever a single carb adapter plate?

An order is a piece of paper.....

If the firewall plenum cutout was completed, (which is the dilemma here), does the car get built or pulled off the assembly line

The Cowl cutout was the responsibility of the dealer or owner, never performed at Fisher or Chevrolet.

Well then it means no parts leave the assembly line in the trunk.

Firewall plenum air cleaner cutouts were never done on the assembly line. That was left for the original purchaser to do after delivery. Some paid the dealer to cut and install the air cleaner, some self installed. All factory consumer ordered plenum air cleaner assemblies were supplied in the trunk.

[David K]

So the standard air cleaner assembly was installed?

Yes.

The rally wheel caps were placed in the trunk.

We're all hubcaps delivered in the trunk as well?

In the April 1972 issue of Car Craft, there was an interesting article about Smokey Yunick developing a single carburetor cross-ram intake manifold for use in the 1970 Trans Am series:

Mark,
Smokey fixed all of the issues with the Cross-Rams internals to make it work better. Smaller plenum, shorter runners. Also, racers did more modifications (as seen in the article) to achieve even more. I believe IF Chevrolet continued with the factory involvement in Trans-Am racing for 1970, they would have used Smokey's design Cross-Ram. As noted in the article, GM did attach a part number to it. However, it was a little too late by then. The show was over.

I have the 1970-1974 Camaro FIA docs; no optional manifold is listed.

Chevy still had some involvement; there are HD front brakes, a taller steering knuckle and steel fender flares listed.

If you look in the front of the AIM it lists what was stowed in the luggage compartment.  For 67 it's  UPC 0 Sheet C1 and 1.5

Thanks Pete....I forgot it was there. 0C1 for 1968
