Author Vizard covers blending the bowls, basic porting procedures, as well as pocket porting, porting the intake runners, and many advanced procedures. Advanced procedures include unshrouding valves and developing the ideal port area and angle.
Extracting maximum torque and horsepower from engines is an art as well as a science. David Vizard is an engineer and more aptly an engine building artist who guides the reader through all the aspects of power production and high-performance engine building. His proven high-performance engine building methods and techniques are revealed in this all-new edition of How to Build Horsepower. Vizard goes into extreme depth and detail for drawing maximum performance from any automotive engine. The production of power is covered from the most logical point from the air entering the engine all the way to spent gasses leaving through the exhaust. Explained is how to optimize all the components in between, such as selecting heads for maximum flow or port heads for superior power output, ideal valvetrain components, realizing the ideal rocker arm ratios for a particular application, secrets for selecting the best cam, and giving unique insight into all facets of cam performance. In addition, he covers how to select and setup superchargers, nitrous oxide, ignition and other vital aspects of high-performance engine building.
Over the last 40 years, millions of Chrysler, AMC, and Jeep vehicles have used these differentials, propelling these high-performance vehicles to victory on the street, in drag racing, and other applications. Chrysler used the Dana 60 and BorgWarner Sure-Grip high-performance differentials in the Challenger, Charger, Barracuda, Super Bee and many other renowned Chrysler muscle cars. These differentials have been tied to historic powerhouse engines, such as the Chrysler Magnum and Hemi V8s in stock car, drag racing, and other forms of racing, making history in the process. Jeep CJs and Cherokees have used the Dana 44 and AMC 20 and put these differentials under tremendous loads, which often requires frequent rebuilds. After years of use, these differentials require rebuilding, and of course aftermarket suppliers offer ring and pinion and other parts to upgrade these axles. In this Workbench series title, the focus is on the disassembly, inspection and step-by-step rebuild of the most popular high-performance differentials. Axles and differentials are not incredibly complex components, but there are some specific steps to follow for rebuilding, upgrading, and setting them up properly, and this book demystifies the process and explains it in detail. A book dedicated to the Dana, Sure-Grip, and AMC Jeep axles has never been published before, and Mopar, Jeep and AMC enthusiasts are hungry for this information. The Dana and AMC axles should remain in wide use into the foreseeable future, and therefore there will be a consistent demand for this information. This book will also feature extensive gear and application charts, so the reader is sure to select the correct gear ratio for a particular vehicle and application. Special coverage is therefore dedicated to ring and pinion gears. In addition selecting the best aftermarket and production axle shafts is covered as well as modifying and upgrading the differential housings.
