David Vizard's Guide to Enhancing and Customizing Holley Carburetors

B.N.: This book, not a pamphlet, has color pictures, big type face-easy to see in a dark garage. David Vizard is an encyclopedia of information and anything you need to know about a Holley is in this book.
Will buy again if this one gets lost or catches fire. Looking forward to educating myself with the help of DV's book.

Lars E: Boken är utmärkt, Vizard kan sina saker.
Varning bara att säljaren "Fishpond" är baserad nånstans utanför EU. Det tillkommer alltså 75 SEK till PostNord för att det kommer utifrån och därtill tull och moms. Anmärkningsvärt att detta inte hanteras av Amazon som "Svensk" återförsäljare.

john w.: Vizard’s books are good, he is thoughtful and thorough. First one I read was about the British Leyland ‘L’ series engine, used in the (real) mini, and many other small brit cars. I don’t like those cars much, but the book was excellent. Informative and entertaining. Learn from it and adapt to your brand. This one is the same way- read it to improve your carb understanding, whether or not Holleys are your thing. I have never owned a 4 bbl Holley, but they are common and serve as a good example....something to learn about, develop an understanding, and apply where needed. If this doesn’t sound good, you can stick to adjusting idle speed or replacing the air filter.
This is a person who thinks hard about why things work how they do, and how to make them better. Also, about what might be “how its always been done” but doesn’t really work. His suggested ideas are backed up with testing, not some silly anecdotal evidence. That method of supporting ones opinion is, sadly, common in this sort of book, but Mr. Vizard doesn’t do that. I can’t imagine the time he’s spent learning what went into this and the other books.
Just so you know- It isn’t step by step...

tyler duran: I bought this book not really expecting much as I’ve had decent success tuning Holley carbs in the past simply using the information available from Holley and the Internet. After reading it a lot of “why” questions I had about these carbs were no longer a mystery.

The book covers MUCH more than Holley carb tuning too thankfully. The book merged all of the important tuning aspects that directly impacts the carb’s tune such as: ignition timing, intake manifold selection, cam profiles, and head flow. And this isn’t done in the generic way manufacturers market there products. This book provides incredibly detailed explanations on why these different components are used and or tuned the way that they are.

Even better still is the countless dyno grace h comparisons of different combinations, showing the affect of each individual component selection and tune.

The book gives MANY different tuning methods too. Each method of tuning is discussed, evaluated, and then demonstrated.

What this book isn’t: it is not a complete replacement for the standard tuning guide included with all Holley carburetors. These carbs simply aren’t that complex and the...

marc st laurent: I always like the way David Vizard wrote in car magazines so I jumped at the chance to own and study his carb manual , I already have a good understanding of Holley Carbs and this manual really helped me understand the nuances of tuning one

Dave Rauhut: very in-depth, and informative. Technical wording is understandable and offers a lot of insight into the carb. Only thing it lacks is examples using a 6 cylinder engine.I am new into modifying engines, and this book has helped me to really understand what I will be doing .

J. Garcia: I was hoping that this book would help me rebuild my carb, but not so much. What it did do was help me understand how a Holley works and what can be done to tune the carburetor. I'm still trying to wrap my head around the Power Valves and their respective sizes. I understand that it's related to manifold vacuum, but still trying to figure out how it works.

The book goes into detail about the air bleeds, different booster styles, and also modifications that can be done to get more CFM flow out of your carb that doesn't even require boring out out. All it takes is improving the air flow through the carb.

If you're looking for a book to help you rebuild your carb while making modifications along the way, then this isn't it. If you're looking for a book that helps you really understand how a Holley works and how to get the most out of your Holey, then this is it. This book would be great as a supplement to other literature that details the steps required to rebuild your Holley.

As for me, I had troubles with my Holley and that's why I bought this book. I temporarily replaced the 759 double pumper with an Edelbrock. It's running better, but I'm still wanting to go...
