Having chatted with Cliff previously via email, I was happily surprised that he had finally put his wisdom to paper. While it's clear when reading this book that he is a Pontiac fan, he does a good job on the Chevy, Buick, and Oldsmobile Quadrajets also.
In this book you'll find practical rebuilding, repairing, and performance tips. I really like the fact that he covers the repairs that often have to be made to the venerable Quadrajet, now that the one that is on our vehicles is probably well over 30 years old! If you are wondering how to repair that stripped fuel inlet thread, or how to modify your idle air bypass, you will find that information in this book. Not only does this book do a fantastic job covering repairs and performance modifications in depth, the photo's are large, detailed, and relevant.
Discussion of operation of the various circuits is included. The various models and improvements over the years is explained. With this info you will be well prepared to select the right Q-jet for your vehicle.
This work on Rochester carbs is important because the Rochesters, especially the Quadrajet, are vastly underated. There is a very good chance that you could run a Quadrajet on your vehicle and gain fuel efficiency without sacrificing power. In this day and age, that is no small consideration. On a 327 Chevy I've run three Quadrajets (7045263, 7043250, and 7029207) against an out of the box fresh Holley 6619. The best Quadrajet, which happened to be new also, beat the Holley on an identical course by about two miles per gallon with no perceived loss of performance! One of the other Qj's was new also, the other one was rebuilt to stock specs on the primary side, and richened up on the secondary side. The bottom line is that out of the three Quadrajets tested on my vehicle, three of them beat the Holley in the mpg category. Of course, your results may differ, but my point is that you should not overlook the Quadrajet when planning your next street engine build. My motivation to run the Quadrajet came largely from Doug Roe's book, however, there are a lot of points in this work that do not appear in the book by Doug Roe. If you do a search you can find further results from my "test" online. Just type in the carburetor numbers and Holley.
Even if you already have Doug Roe's book on Quadrajets, you'll want this one too. Besides the wealth of photographs, and up to date information, you'll notice that he even covers the Edelbrock Quadrajets as well. Lot's of information for the money.
