How To Swap & Build Max Performance Chevy LT-Series Engines

In 1992, General Motors introduced the LT1 V-8 engine. This upgraded design, based on the traditional (since 1955) small-block V-8, marked a significant step forward for GM, as the engine was designed to be a modern, efficient, computer-controlled powerplant from the start. This was unlike any other V-8 GM had ever built, and the results were outstanding. The LT1, along with its more powerful stablemate, the LT4, raised the bar for performance-oriented small-blocks until the introduction of the LS1 in 1997. The LT1/LT4 engines are powerful, relatively lightweight, and affordable. They powered Chevrolet?s legendary Impala SS (and thousands of similar police cars), Corvettes, and Camaros and remain viable choices for enthusiasts today. This book investigates every component of these engines, discussing their strong and weak points and identifying characteristics. Upgrades and modifications for both improved power production and enhanced durability are described and explained in full. All relevant factory casting numbers are listed. Aftermarket component upgrades for improved street and track performance are defined clearly and in great detail. First book to specifically address performance modifications for the LT1/LT4 engines. LT1/LT4 engines powered Corvettes, Camaros, and Impala SS cars from 1992 to 1997. LT1/LT4 engines are an excellent and affordable platform for major performance improvements. The GM LS engine has dominated the crate and engine-swap market for the past 20 years, and now the new LT engine has become a popular crate engine for swap projects as well. As essentially the next-generation LS, the LT features a compact footprint, lightweight design, and traditional V-8 pushrod architecture similar to its predecessor, so it swaps easily into many classic cars, hot rods, and even foreign sports cars. The new LT1/LT4 takes a bold step forward in technology, using active fuel management, direct injection, an upgraded ignition system, continuous variable valve timing, and a wet- or dry-sump oiling system. With this advanced technology and higher performance, more engine swappers are using the LT platform. Swapping expert and longtime author Jefferson Bryant presents thorough instruction for each crucial step in the LT swap process. Although the new LT shares the same basic engine design with the LS, almost all of the LT engine parts have been revised and updated. As a result, the mounting process has changed substantially, including motor-mount location, K-member mounting process, and component clearance; all these aspects of the swap are comprehensively covered. All other important aspects of the swap process are covered, including accessory drives and cooling systems, engine management systems, tuning software, controllers, and exhaust, so you can install the LT in popular GM A- and F-Body platforms as well as almost any other chassis. Solutions for the major swapping challenges, parts compatibility, and clearance issues are provided. Muscle car, hot rod, truck, and sports car owners have embraced the new LT platform and the aftermarket has followed suit with a wide range of products to facilitate swap projects. This book affords comprehensive guidance so you can complete a swap with confidence. • First-ever book on LT swaps • LT engines are an evolutionary upgrade to the LS platform • Crate engine and transmission combos are thoroughly covered
