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.

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.

The needs of a true competition engine are quite different than those of the engine under the hood of a typical commuter car. From the basic design needs, to the base component materials, to the sizes of the flow-related hardware, to the precision of the machining, to the capabilities of each pertinent system, very few similarities exist. Many books exist showcasing how to make street-based engines more powerful and/or durable. This book is different, in that it focuses purely on the needs of high rpm, high durability, high-powered racing engines. It begins by looking at the raw design needs, and then shares how these needs are met at the various phases of an engine's development, assembly, testing and tuning. This book features reviews of many popular modern tools, techniques, products, and testing/data collecting machinery. Showing the proper way to use such tools, how to accurately collect data, and how to use the data effectively when designing an engine, is critical information not readily available elsewhere. The special needs of a competition engine aren't commonly discussed, and the many secrets competition engine builders hold closely are openly shared on the pages here. Authored by veteran author John Baechtel, Competition Engine Building stands alone as a premier guide for enthusiasts and students of the racing engine. It also serves as a reference guide for experienced professionals anxious to learn the latest techniques or see how the newest tools are used. Baechtel is more than just an author, as he holds (or has held) several World Records at Bonneville. Additionally, his engines have won countless races in many disciplines, including road racing and drag racing.
