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.

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 complete practical guide to successfully modifying cylinder heads for maximum power, economy and reliability. Applies to almost every car/motorcycle (not 2-stroke) and to all road and track applications.

This book shows you how to choose the best cylinder head for your application. It covers both Gen I and Gen II small-block Chevy versions, occasionally touching on the Gen III and Gen IV production versions. This book taps into some of the best small-block Chevy cylinder head resources this country has to offer with a combination of insight and best guesstimates, because much of what we know about port design and airflow management falls under the category of art rather than science.

Professional advice on camshafts, rocker arms, lifters, valve springs, retainers, and morecomplete with more than 300 step-by-step, how-to photos and test charts.

GM's LT1/LT4 engines represented the highest level of small-block V-8 develop-ment for the period between the legendary small-block Chevrolet and the introduction of the LS-series V-8. They powered all of the hottest production vehicles of the 1990s, including the Corvette, Camaro/Firebird, and Caprice/Impala SS. These enhanced small-blocks were reliable and strong, and can be built to impressive performance levels on a relatively small budget, with the right upgrades. This book guides you through the factory and aftermarket components of the LT1/LT4 engines, offering sound performance advice and recommendations. Additionally, complete engine buildup recipes are provided, along with their respective horsepower and torque levels. You can follow the advice of experts and achieve targeted results for your own project.

In this book, McClurg reviews the often-mystical subject of nitrous oxide injection systems with a level head and a clear purpose. This book educates the reader on the properties of nitrous oxide and most-effective way to design, install, and tune complete systems. A definite focus on safety and a need to answer the typical questions associated with the use of nitrous oxide is highlighted, and several complete installations are featured.
