Chevy Big-Blocks: How to Build Max Performance on a Budget
As a follow-up title to his How to Build Max-Performance Chevy Big-Blocks on a Budget, master engine builder David Vizard takes big-block Chevy engine building to the next level and shows how to build these extreme high-performance engines without breaking the bank. It goes well beyond basic performance techniques and delves into exceptional detail on each component group of the engine. Vizard shows you how to build the ultimate big-blocks for the street: engines that are up to 850 hp on 91-octane pump gas, which is a monumental achievement.
The Chevy big-block has been substantially under-valved, and the key to getting the best performance from this engine is to deal effectively with this design limitation. Vizard explains how to minimize intake-valve shrouding, reveals the science behind all cam-timing events, and explains how to arrive at the correct valve overlap for maximum efficiency. Vizard also covers the nuances of piston ports, rings, and connecting rods so that the rotating assembly is strong and working at its peak. Finally, a special section presents a number of max-performance big-block sample builds.
This volume includes a huge range of cutting-edge aftermarket parts and advanced tuning techniques. If you're serious about building a max-performance Chevy big-block engine for the street or track, you owe it to your engine and yourself to include this book in your automotive library.
