In the tradition of the original small-block Chevrolet introduced in 1955, the Gen III Chevy small-block V-8 has revolutionized the high performance V-8 world.

If you pay attention at all to the current street scene, you know that 450+ horsepower head, cam, and intake-equipped LS1 and LS6 engines are terrorizing the Mustang and import crowd. And with the recent barrage of aftermarket support, the LS1, LS6, and Vortec engines have officially established their position at the top of the modern hot-rodding food chain.

Whether you want to add a supercharger or turbocharger, build an all-motor menace, or just add a few bolt-ons, How To Build High-Performance Chevy LS1/LS6 V-8s will show you how. And, as any hardcore LS1/LS6 enthusiast can tell you, if you ever want to get serious about Gen III V-8 performance, you're going to have to learn to remove and reinstall your engine. That's why this book includes an entire chapter, with a total of 150 photos, to show you how to do exactly that in a Camaro, Firebird, C5 Corvette, and a full-size truck.

Then, rather than spending chapter after chapter explaining advanced engine theory, author Will Handzel, Group Manager of GM Performance Parts, uses elaborate step-by-step photo sequences (over 550 photos in all!) to demonstrate some of the most successful parts combinations he has come across. With everything from bolt-on parts to a 1,200-hp, 387-ci supercharged monster, this book has it. Take a look—you won't be disappointed.
