Increase the power output of your A-Series! This fact-filled guide covers all aspects of engine tuning in detail, including filters, carburation, intake manifolds, cylinder heads, exhaust systems, camshafts, valve trains, blocks, cranks, con rods and pistons, plus lubrication systems and oils, ignition systems, and nitrous oxide injection. Applicable to all A-Series engines, small and big bore types, from 803 to 1275cc.

Renowned engine builder and technical writer David Vizard turns his attention to extracting serious horsepower from small-block Chevy engines while doing it on a budget. Included are details of the desirable factory part numbers, easy do-it-yourself cylinder head modifications, inexpensive but effective aftermarket parts, the best blocks, rotating assembly (cranks, rods, and pistons), camshaft selection, lubrication, induction, ignition, exhaust systems, and more.

Extracting maximum torque and horsepower from engines is an art as well as a science. David Vizard is an engineer and more aptly an engine building artist who guides the reader through all the aspects of power production and high-performance engine building. His proven high-performance engine building methods and techniques are revealed in this all-new edition of How to Build Horsepower. Vizard goes into extreme depth and detail for drawing maximum performance from any automotive engine. The production of power is covered from the most logical point from the air entering the engine all the way to spent gasses leaving through the exhaust. Explained is how to optimize all the components in between, such as selecting heads for maximum flow or port heads for superior power output, ideal valvetrain components, realizing the ideal rocker arm ratios for a particular application, secrets for selecting the best cam, and giving unique insight into all facets of cam performance. In addition, he covers how to select and setup superchargers, nitrous oxide, ignition and other vital aspects of high-performance engine building.

The photos in this edition are black and white.Acclaimed automotive technical writer David Vizard examines the finer points of carburetors and intake manifolds, looking for the smallest of modifications and upgrades which often result in large performance gains. How to Build Horsepower: Volume 2 includes Carter, Holley, Predator, Weber, Dellorto, and Mikuni carbs, dozens of factory and aftermarket manifolds, tunnel ram intakes, etc. Also covers carb calibration methods, analysis of different designs, mixture ration, test results of various carb and intake combinations.

Author Vizard explains how the enthusiast needs to shape the combustion chambers and smooth out ports for maximum performance. Of key importance, he shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber. It covers blending the bowls, a most basic porting procedure, but it also covers pocket porting, porting the intake runners, and many advanced procedures. These advanced procedures include unshrouding valves, porting a shortside turn from the floor of the port down toward the valve seat, and developing the ideal port area and angle. All of these changes combine to produce optimal flow velocity through the engine for the maximum power.

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. n "David Vizard's Holley Carburetors: How to Super Tune and Modify," 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. 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.

The Chevy big-block has been installed in millions of cars and trucks over the past 50 years, including Camaros, Chevelles, Corvettes, Impalas, and a multitude of trucks. And extracting maximum performance has been the goal of many engine builders. In this follow-up to his previous Chevy performance book, master engine builder David Vizard takes big-block Chevy engine building to the next level. But he shows how to build these extreme high-performance engines without breaking the bank. The discussion goes well beyond the basic performance techniques and delves into exceptional detail on critical components of the engine. The Chevy big-block has been substantially undervalued, and the key to getting the best performance from this engine is to effectively deal with its design limitations. Vizard explains how to minimize intake valve shrouding on the block and unlock at least 20 hp. He also reveals how to arrive at the correct valve overlap for maximum volumetric efficiency. Heads must properly flow an enormous amount of air so selecting the best heads for a setup are detailed. Vizard covers the nuances of piston crown shapes, rings, and connecting rods to ensure that the rotating assembly is strong and working optimally. Chapters also include lubrication, fuel injection, single carb and tunnel ram intakes, ignition, and exhaust. A special section presents a number of max-performance big-block sample builds.
