In this book, expert engine builder and veteran author Mike Mavrigian explains and illustrates the most discriminating engine building techniques, so the engine is perfectly balanced, matched, and optimized. Balancing and blueprinting is a time consuming and exacting process, but the investment in time pays off with superior performance. Through the process, you carefully measure, adjust, machine and fit each part together with precision tolerances, optimizing the design and maximizing performance. The book covers the block, crankshaft, connecting rods, pistons, cylinder heads, intake manifolds, camshaft, measuring tools and final assembly techniques.
For more than 50 years, balancing and blueprinting has been an accepted and common practice for maximizing performance. An enthusiast or professional that invests the time to precisely build an engine in this fashion will be rewarded with an engine that will run strong and last for years. This book provides an unprecedented level of detail and instruction on the process of balancing and blueprinting your engine.
