GM's LS1 engine shook the performance world when it was introduced in the 1997 Corvette. It set a new precedent for massive power, light weight, and impressive fuel economy. Often referred to as the Generation III engine, it (and its most recent iteration, the Gen IV) is the high-water mark for performance V-8 engines. The latest version, the LS9, makes some 638 hp from just 6.2 liters, far eclipsing even the mightiest big-blocks from the muscle car era. And it does so while meeting modern emissions requirements and delivering respectable fuel economy. With these credentials, it is no wonder that the LS-series engines are among the most popular engines for high-performance applications. They respond well to modifications and can handle massive power, whether naturally-aspirated, nitrous-injected, or by way of forced induction. "How to Build and Modify GM LS-Series Engines" shows what modifications are needed to acheive any performance goal you desire. Topics include block selection and modifications, crankshaft and piston assemblies, cylinder heads, camshafts, valvetrain, intake manifolds, fuel system, and header selection. This is the ultimate resource to build the ultimate LSX engine!
