High-Performance Cams & Valvetrains & New Hemi Engines How To Build Max Performance (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.

The New Hemi engine has an aggressive persona and outstanding performance. Powering the Challenger, Charger, Ram trucks, and other vehicles in the Chrysler lineup, this engine produces at least one horsepower per cubic inch. Unleashed in 2003, it has been offered in 5.7-, 6.1-, 6.2-, and now 6.4-liter displacements. With each successive engine introduction, Chrysler has extracted more performance. And with the launch of the Hellcat and Demon 6.2-liter supercharged engines, Chrysler built the highest horsepower production engines ever made, at 707 hp and 840 hp, respectively.

This third-generation Hemi carries on a high-performance Chrysler tradition and is considered the most powerful and “buildable” new pushrod V-8 engine on the market today. Mopar engine expert and veteran author Larry Shepard reveals up-to-date modification techniques and products for achieving higher performance. Porting and modifying the stock Hemi heads as well as the best flow characteristics with high lift are revealed. In addition, guidance on aftermarket heads is provided.

A supercharger is one of the most cost-effective aftermarket add-ons, and the options and installation are comprehensively covered. Shepard guides you through the art and science of selecting a cam, so you find a cam that meets your airflow needs and performance goals. He details stock and forged crankshafts plus H- and I-beam connecting rods that support the targeted horsepower, so you can choose the best rotating assembly for your engine. In addition, intake manifold and fuel systems, ignition systems, exhaust systems, and more are covered.
