While many of today's modern cars have moved past carburetors and into high-tech fuel-injection systems, most cars from the highly collectible eras are still running carburetors. Carbs are comparatively inexpensive, highly tunable, and do not require laptops, expensive tuning equipment, or computers to function. And by far, the most popular carb still in use is the Holley carb.
In David Vizard's How to Super Tune and Modify Holley Carburetors, best selling author Vizard explains the science, the function, and most important, the tuning expertise required to get your Holley carburetor to perform its best for your performance application, whether it's street, strip, supercharging, or race applications. Holley has been a best-selling subject for years, and this much-needed update guides you through the traditional 4150 Double Pumper, Dominator, and 4160 vacuum secondary models, as well as all the recent releases from Holley, including the Ultra Street Avenger and Ultra HP Series Carbs.
With its high degree of tuning ease, and with all the new models coming into the market, the knowledge of an expert like Vizard is a requirement to meet your performance goals, now more than ever. This book is an essential addition to any hot rodder's library.
