David Vizard S Chevy Big Blocks

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.

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. Extracting maximum performance has been the pursuit of engine builders ever since this engine was new in 1964. As a follow-up title to his How to Build Max-Performance Chevy Big-Blocks on a Budget, master engine builder David Vizard takes big-block Chevy engine building to the next level and shows how to build these extreme high-performance engines without breaking the bank. It goes well beyond the basic performance techniques and delves into exceptional detail on each component group of the engine. Vizard shows you how to build the ultimate big-blocks for the street: engines that are up to 850 hp on 91-octane pump gas, which is a monumental achievement. The Chevy big-block has been substantially under-valved, and the key to getting the best performance from this engine is to deal effectively with this design limitation. Vizard explains how to minimize intake-valve shrouding, reveals the science behind all cam-timing events, and explains how to arrive at the correct valve overlap for maximum efficiency. Vizard also covers the nuances of piston ports, rings, and connecting rods so the rotating assembly is strong and working at its peak. Finally, a special section presents a number of max-performance big-block sample builds. This volume includes a huge range of cutting-edge aftermarket parts and advanced tuning techniques. If you're serious about building a max-performance Chevy big-block engine for the street or track, you owe it to your engine and yourself to include this book in your automotive library.

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.

Hundreds of photos, charts, and diagrams guide readers through the rebuilding process of their small-block Chevy engine. Each step, from disassembly and inspection through final assembly and tuning, is presented in an easy-to-read, user-friendly format.

Readers are shown how to get the optimal machining performed, select the ideal parts, and assemble the strongest big block engine for a budget of $1,500 to $15,000.

Porting heads is an art and science. It takes a craftsman's touch to shape the surfaces of the head for the optimal flow characteristics and the best performance. Porting demands the right tools, skills, and application of knowledge. Few other engine builders have the same level of knowledge and skill porting engine heads as David Vizard. All the aspects of porting stock as well as aftermarket heads in aluminum and cast-iron constructions are covered. Vizard goes into great depth and detail on porting aftermarket heads. Starting with the basic techniques up to more advanced techniques, you are shown how to port iron and aluminum heads as well as benefits of hand and CNC porting. You are also shown how to build a high-quality flow bench at home so you can test your work and obtain professional results. Vizard shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber. The book covers blending the bowls, a basic porting procedure, and 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 maximum power.

Turn your mouse engine into a hi-performance power factory with tips and secrets from David Vizard. In this volume you'll learn port mods, compression ratios, head preparation, offsetting and more head-work to get the most from your mouse.

In How to Build Killer Big-Block Chevy Big-Block Chevy Engines, author Tom Dufur reviews the commonly available factory parts along with many aftermarket offerings, and discusses the advantages of both. Additionally, he includes popular buildup recipes and showcases the dyno results, proving theories and sharing in-depth research. Dufur's decades of experience designing, assembling, tuning, and racing the big-block Chevy engine truly shines through. A wealth of full-color photos, charts, and graphs makes it easy to understand the critical points of these great engines.
