Automotive Machining: A Guide to Boring, Decking, Honing & More
The photos in this edition are black and white.
Maximize the potential of your engine build by using the automotive machining procedures, including cylinder boring, align boring/honing, decking, valve seat cutting, cam tunnel boring, and much more.
A detailed, authoritative, and thorough automotive engine machining guide for the hard-core enthusiast has not been available until now. Mike Mavrigian, editor of Engine Building Professional, walks you through each important machining procedure. A stock 300-hp engine build has far different requirements than a 1,000-hp drag race engine, and Mavrigian reveals the different machining procedures and plans according to application and engine design. He also shows you how to inspect, measure, and evaluate components so you can make the best machine work choices. Multi-angle valve jobs, altering rocker arm ratios, re-conditioning connecting rods, and machining and matching valvetrain components are also covered.
Machining is an essential part of high-performance engine building and stock engine rebuilding. Although you may not own the expensive tooling and machining to perform all or any of the machining required for a quality build, understanding the principles, procedures, and goals for machining is vital so you can guide the machining process when outsourced. Classic and older engines typically require extensive machining and almost every major component of engine, including block, heads, intake, crankshaft, and pistons, requires some sort of machining and fitment.
Whether you're an enthusiast engine builder or prospective machining student who wants to pursue a career as an automotive machinist, this book will provide insight and in-depth instruction for performing the most common and important machining procedures.
