High-Performance Cams & Valvetrains & How To Build & Modify Gm Ls-Series Engines (2 Book Set)

Experience the Power of High-Performance Cams & Valvetrains: Theory, Technology, and Selection

Camshafts are the driving force behind any four-stroke engine, serving as both the coach and conductor. Whether you're dealing with a classic flathead or a cutting-edge Formula 1 machine, the performance of your engine hinges on the precise timing and operation of its valves. While valvetrain configurations may vary across applications, the fundamental principles remain constant. That's why this book delves into the language, setup, dynamics, energy, and pressure aspects of valvetrains, offering insights applicable to engines ranging from sub-15-hp go-karts to 500-plus-hp street beasts and modern 1,500-plus-hp NHRA Pro Stock monsters.

In High-Performance Cams & Valvetrains: Theory, Technology, and Selection, Billy Godbold—a former farm kid turned physicist—shares his extensive quarter-century of experience working with valvetrains at renowned companies like Comp Cams, Lunati, Crane Cams, and Edelbrock. Drawing from his collaborations with professional teams in NASCAR, NHRA, road racing, dirt track racing, offshore racing, and land speed racing, Billy provides a unique perspective on valvetrain systems. Through his lighthearted and analogy-rich approach, this book simplifies complex concepts without compromising essential details.

Featuring specific configurations and applications, High-Performance Cams & Valvetrains equips you with practical techniques and examples for optimizing camshafts and valvetrains in various scenarios. Whether you're working with intakes, headers, superchargers, turbochargers, fuels, carburetors, or modern EFI applications, this book offers invaluable guidance. Whether you're building a classic hot rod (Chevy, Ford, Chrysler, and more), a modern performance machine (LS, Hemi, Coyote, or Godzilla), or a competition engine (road racing, circle track racing, or drag racing), you'll discover how to modify your valvetrain system effectively to unlock the maximum potential of each component, ultimately helping you achieve your unique goals.

When first introduced in the 1997 Corvette, GM's LS1 engine shook the performance world. Its combination of massive power, light weight, and impressive fuel economy set new precedents for performance engines--and continues to do so generation after generation.  The latest version, the LS9, makes some 638 hp from just 6.2 liters, far eclipsing even the mightiest big-blocks from the muscle car era--while meeting modern standards for emissions and fuel economy.  It's no wonder, then, that the LSX engines have become some of the most popular for high-performance applications.  

 For those who want to build or modify their LS engine, this book provides the most detailed and extensive instructions ever offered.  Whatever your performance goals might be, How to Build and Modify GM LS-Series Engines. The LSX engine, first introduced in the 1997 Corvette, is one of the most popular for high-performance applications.  And for those who want to build or modify their LS engine, this book provides the most detailed and extensive instructions ever offered.  Whatever your performance goals might be, How to Build and Modify GM LS-Series Engines shows you what modifications are needed and how to make them.  Its topics include crankshafts and piston assemblies, cylinder heads, camshafts, valvetrain, block modifications, intake manifolds, fuel system, header selection, and setting up ring and bearing clearances for particular uses.  shows you what modifications are needed and how to make them.  Premier LS engine technician Joseph Potak addresses every question that might come up, covering topics including crankshafts and piston assemblies, cylinder heads, camshafts, valvetrain, block modifications, intake manifolds, fuel system, header selection, and setting up ring and bearing clearances for particular uses.  In short, this book is the ultimate resource for building the ultimate LSX engine.
