Kurt S. - I'm sorry if I implied that GM printed them. Helm Inc. does a lot of GMs printing and is one of probably a number of companies that does the printing for GM. You're right about some outside companies putting manuals/books together. But wouldn't you agree that the data that is supplied comes from the General?
Greg R.- Nice work on that chart and page! Great info! The Price Schedule that I have came with an almost complete set of Technical Service Bulletins, Chevrolet Service News and other stuff. I found it a few years ago. The Service Department binder that everything came in does have titled dividers for the Price Schedule.
One of the source books I was using is (as Greg R. described it in his response, a #4) a Chevrolet Price Schedule (8 1/2" x 11"). The cover page is dated November 1, 1965, 1st mailing. Most of the pages inside are Dated February 1, 1966 that reflects an updated mailing was put in at some point. The other source book is called Chevrolet Finger-Tip Facts. It is also an 8 1/2" x 11" book and comes in a 3 ring binder. It's like a cross between the Price Schedule book and the Dealer showroom book (Sales Album). It doesn't have fabric samples and is more technical. It was used as a supplement to the "Sales Album". I figured that not everybody has seen some of these books before so, I've put some links here to pictures of the manuals.
The first 2 links are from the 1966 Finger-Tip facts. The first one is the cover page and the second one is the Chevrolet Power Teams page. On the Power Teams page you can see the engine/transmission/axle combinations that were available. This Power Teams page is only for Chevrolet full size passenger cars.

The next 3 links are for the 1966 Pricing Schedule that also reflects this information. I included the Chevelle Power Teams page as well.

I did have a conversation with a great friend of mine who has worked for GM for quite a while and he started to tell me how GM came up with these combinations. I don't have it all sorted out on my end, but he is being kind enough to send me some engineering data on how they did this. I can tell you that it involved some obvious things like vehicle weight, engine torque and something I never figured like how many engine revolutions per mile. I'll see what info is in there when it shows up.
