How to Rebuild the Big-Block Chevrolet
The Mark IV Chevrolet big-block, made from 1965 to 1976, produced legendary performance and is one of the greatest big-blocks of all time. This design was a giant performance leap ahead of the old Chevy wedge big-block. The Mark IV featured canted valves, large intake ports, and an efficient head design for vastly increased air/fuel flow, better combustion, and huge horsepower. With a big-block under the hood, the Camaro, Chevelle, Corvette, and other Chevys became some of the most desirable ultra-high-performance cars of all time. How to Rebuild the Big-Block Chevrolet covers the best techniques for rebuilding the renowned 366-, 396-, 402-, 427-, and 454-ci big-block engines.
With exceptional clarity and insightful detail, this book explains engine removal, disassembly, parts inspection, selection of machine work, initial and final assembly, tuning, and break-in.
Through 500 photos and extremely detailed instruction, each step-by-step procedure explains professional techniques for rebuilding these engines. In addition, high-performance upgrades are covered as well as torque specs for major components, setting cylinder firing order, main bearing cap torque sequence, and much more. This volume provides an unparalleled level of information for rebuilding a big-block Chevy, so your rebuild project is hassle-free and successful.
