I went through the latest NCRS Driveline. I am looking for a book on the old C1 and C2 Fuel Injection units. I would like to learn to break them down, rebuild and tune them. Is there a recent book on this?

Re: C1 & C2 Fuel Injection Units
David,
I do not know of any recent books on the topic, nor have I seen any older books on this topic in the NCRS bookstore. The Chevrolet service manuals (ST12 in particular) do have some basic tuning and service information, but it sounds like you want something more detailed. Some people on eBay are always selling old Rochester manuals, so I would recommend searching there for something more suitable (a couple of links are provided below). I don't have either of these books so I can't comment on their usefulness.

Re: C1 & C2 Fuel Injection Units
Take a look at the 1963 Corvette Shop Manual, section 6M. It has a general discussion of operation and then goes into maintenance and adjustments. The section makes use of a Manometer to set up the rich and lean stops - you can now use an exhaust gas analysier. If you plan to install and run one make sure you add real LEAD to the gas for lub of hi pressure pump.Comment

Such a book is needed
There are no recent books on properly repairing 40 year old Rochester injection units.
There are many old GM, Helm, and aftermarket publications on repairing these units when they were still within the warranty period. In other words, they make no mention of good/bad reproduction parts, how to repair worn out factory parts that aren't reproduced, or how to tune the units for non-stock cams, larger displacement engines, or any form of racing. They definitely don't say how to correct factory design nightmares such as those communist '57 - '61 chokes. The old publications don't even bother to correct the factory tuning spec mis-prints. The magazine articles that have been written don't offer much more help other than identification tips.
By the way, please do not let any KEROSINE based "lead" additive run through your FI unit. The high pressure FI gear pumps do not require any lead to fuction properly. These pump gears are submerged in gasoline. They run many hundreds of degrees cooler than exhaust valves and are in absolutely no danger of metal erosion from lack of lubrication.Comment

Re: Such a book is needed
All of the above is good info----------and, basically, the ONLY info. For over 30yrs I have been collecting any and all info, manuals, articles, reports, etc, etc, about Rochester FI that I can get my hands on. There have also been a couple of articles written by some of the old time FI gurus (Bill Thomas, Norm Berger) which also have some helpful info. NONE of the individual above items are extremely beneficial for a do-it-yourselfer who is not familiar with the Rochester units. BUT, ALL OF IT collectively makes a great reference library. I have been messing with and rebuilding FI units for over 30yrs----------------AND I'M STILL LEARNING! The unit on my car is somewhat modified and made up from parts between 58 and 65. This is simply because that is what it took to achieve what I wanted from an FI unit (early appearance, but dependability of later units)!
I would first recommend that you acquire the FI publications which were originally available from GM (there are several sources that have reprints for sale). READ and STUDY them and study the schematics. In time, you will begin to develop an understanding of how they work. In theory, an FI unit is not a whole lot different from a big 1bl carb! MANY reproduction parts are available from several sources. Some are OK, others are best. You need to privately email people for advice.
Jerry Bramlett,
THANK YOU SO MUCH, I got the beads!Comment
