    The Holley carburetor is an icon in the performance industry. Thirty, forty, even fifty years ago, if you looked under the hood of any modified or performance car, you more than likely would discover a Holley carburetor lurking there. Often, many enthusiast's first modification is swapping out the factory induction system for a new Holley 4-barrel carb and intake manifold.

    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 importantly, 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.
