I found this while digging around for head specs.

Eco Handbook

This Handbook is more geared towards the Cavalier and Sunfire GM Drag Cars rather than the Cobalt ones like in the Eco Cookbook.

It has some interesting stuff in it. Theres a download link in the file. You have to join to save it but I have it on my hard drive if anyone wants it emailed to them.

I actually have 2 of the CD from GM, one has bonus racing photo's. These are the original ones. I also have a couple of the original build books, orange ones.
