(More customer reviews)Rebuilding a Rochester can be a little intimidating. Let's face it, you can't successfully work on something that you don't understand. If you read this book before you begin, you will understand what the function is of every part that you'll see on your Qj. If you've rebuilt a few Rochesters before and need to fine tune a Quadrajet for a performance engine, this book will answer most all of the questions that you might have.
Roe does an excellent job discussing carburetor theory. He shows clear, large photos of each carb circuit. The choke system on a Quadrajet can be very complex, so I've found myself pulling this book off the shelf time and again and using the excellent illustrations to figure out just how the linkage is supposed to go. He also included a helpful section on building for performance, and fixing idle problems associated with long duration camshafts.
This appears to be the later version of this book. Therefore, it also contains tips on rebuilding the dreaded "CCC" or feedback carb, also know as the electronic Quadrajet. The first version had more information on the 4GC and 2G carbs, but there is still some information provided on each.
I would like to point out one area that I disagree with the author about. Unless you are doing a concours restoration, avoid the 1965 - early 1967 Quadrajets. First of all, the pressure regulated fuel inlet valve (a deviation from a normal needle and seat) is unavailable. Most people won't even know what you are talking about when you mention it. A conversion kit to convert to a conventional needle and seat is included with most rebuild kits, but Roe recommends avoiding these. Secondly, it appears that the "issues in the field" that he mentions, were probably engine fires. Not something that I want to take a chance with.
Roe's 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 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! My motivation to run the Quadrajet came largely from Roe's book. If you would like to read more about the Quadrajet - Holley comparison, type the carburetor numbers and Holley into a search engine.
Having read just about everything in print regarding Rochester carburetors and having rebuilt somewhere between fifty and one hundred Quadrajets over the last twenty years or so, I strongly recommend this book. In short, if I was looking to buy a book on Quadrajet carbs, this is the book I would buy. Roe does the builder a huge service with the many photos he uses to accompany the text. He also gives excellent tips on how to handle some of the more difficult tasks involved when rebuilding a Quadrajets as well as things to look for when troubleshooting. You will hugely increase your chances of a successful Quadrajet rebuild if you read this book first.
