Part I

LS GEN IV

In 2005, GM released the Gen IV engine family, which contains many upgrades over the Gen III. Increased displacement and several new features, such as better high-RPM flowing heads and updated camshaft sensing technology, produced a significant step forward in performance. The Gen IV LS engine lineup included iron-block 4.8L, 5.3L, 6.0L, and 6.2L V-8s while the cast-aluminum-block LS engines offered 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L displacements. The stock LS Gen IV engines power the Camaro, Corvette, and other high-performance cars, SUVs, and trucks. In a certain sense, the LS is the perfect marriage of traditional cam-in-block engine architecture along with cutting-edge head design, modern electronics, and advanced cam technology.

While the Gen IV engines deliver exceptional stock-class performance, a myriad of high-performance parts and procedures can unlock the true potential of these engines. Part I provides detailed information and insightful instruction so you can build an engine to fit your specific output targets and budget. Guidance is provided for choosing a complementary performance package and determining the best machining procedures. In particular, this part covers engine blocks, crankshafts and connecting rods, cylinder heads, pistons, camshafts, lifters, rocker arms, oiling systems, and EFI and intake systems. In Part II, the author provides detailed and revealing instruction for completing two high-performance Gen IV engine builds.
