This book covers how to build Mopar's 383-, 400-, 413-, 426-, and 440-ci engines to power levels of 600 to 900 hp. "How to Build Max-Performance Mopar Big Blocks" discusses how to properly budget your engine build for a specific performance target and how to select a stock or aftermarket block for the desired performance level. The reciprocating assembly (crankshaft, connecting rods, and pistons) is examined in detail, to help you select the right design and material for durability and performance requirements. Cylinder heads and valvetrain configurations are crucial for generating maximum horsepower and torque. This volume discusses all the stock modification options, the best setups, selecting the right machine work, the latest aftermarket head options for producing huge horsepower, and building stroker engines. The camshafts and lifters chapter compares and contrasts use of hydraulic flat tappet, hydraulic roller, and solid flat tappet cams. In addition, the book explains how to optimize fresh and spent fuel, discussing single- and dual-plane intake manifolds, as well as the exhaust-system design to optimize scavenging. Also details engine builds at 600, 700, 800, and 900 horsepower levels to provide insight and reveal what can be done with real-world component packages.
