High-Performance Cams & Valvetrains & How to Rebuild New Hemi Engines 2003-Present (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.

About the Author

Billy Godbold's journey began on a rural Mississippi farm, where his love for science and internal combustion engines took root. Combining these passions, he pursued a Master of Science degree in physics from Florida State University. Throughout his career, Billy has collaborated with legendary figures like Glidden, Lingenfelter, Jenkins, Pink, and Elliot, eventually becoming a trusted consultant for engineering-focused NASCAR teams and original equipment manufacturers.

When Chrysler released the “new” third-generation Hemi engine in 2003, the automotive public placed high expectations on the Hemi’s triumphant return. The Hemi Gen III 5.7L, 6.1L, and 6.2L supercharged and 6.4L engines didn’t disappoint; they produced copious amounts of horsepower and torque while delivering exceptional durability.

Long-time Mopar engineer, racing coordinator, and veteran author Larry Shepard delivers thorough instructions for each crucial step of the rebuilding process. Before commencing engine tear down, Shepard shows you how to perform compression and leak down testing to accurately assess the health of the engine. Disassembly and comprehensive inspection instructions are provided so you can determine and remedy any underlying problems. Expert insight allows you to select the ideal parts package for your rebuild, whether OEM replacement or compatible and complementary high-performance parts are selected. The most pertinent information for the latest machining practices is provided, so you can coordinate with the machine shop to return the block, head, intake, and other surfaces to likenew condition. Assembling the cylinder heads as well as accurately measuring, checking clearances, and test fitting parts is detailed, so you’re sure all components are within spec and ready for final assembly. Finally, comprehensive step-by-step instructions are provided for assembling all components into a completed engine.

The modern Hemi engine is lighter and stronger and offers far better drivability and performance than its predecessors. However, after hundreds of thousands of miles, extreme use, or high-performance applications, these rugged engines require a professional caliber rebuild. With this book, you can confidently complete your Hemi rebuild and get your car or truck back into action.
