Graham Hansen, author of the best-selling SA Design title How To Build Big-Inch Chevy Small Blocks , takes the mystery out of camshaft and valvetrain function, selection, and design. He covers camshaft basics, including a thorough explanation of how a cam operates in conjunction with the rest of the engine and valvetrain. He discusses technical terms like overlap, lobe centerline, duration, lift, and cam profiling. Comparisons between roller and flat-tappet cams are addressed and analyzed. This book covers rocker arms, lifters, valves, valvesprings, retainers, guideplates, pushrods, and cam drives, as well as detailed information on how to degree a cam and choose the proper cam for your application. Finally, matching cams to cylinder heads, analyzing port flow, and proving it all through dyno tests round out this informative volume. Used Book in Good Condition
