The photos in this edition are black and white.

The GM LS-Series engines have made history. These engines produce copious amounts of horsepower and do it very efficiently, and therefore the LS engines have been installed in many GM cars as well as transplanted into hot rods and multitudes of muscle cars. These wildly popular engines have been modified in many ways, and one of the most popular and affordable modifications is stroking an LS engine. By adding more cubic inches, these engines are producing exceptional horsepower and torque.

Author Stephen Kim covers the various models of LS engines, so if you're buying an engine you are able to select the best stroker platform. He also guides you through each crucial step of building a stroker or big-inch LS engine. He starts by discussing the stroker options, the maximum stroke and bore for aluminum as well as iron block engines, and the best cranks, rods, and pistons from various aftermarket suppliers. The budding LS engine builder is then able to select parts or the stroker kit that best fits the particular motor and the budget.

Kim delves into the benefits and drawbacks to stroking the range of LS aluminum and iron block motors. But, he also examines the aftermarket blocks from World, Dart, and GM Performance Parts for stroking. LS engine s are the hottest engine family on the market right now, and for good reason. While there are other LS engine books on the market, this is the only one that specifically addresses increasing displacement as a means of gaining real world usable horsepower.
