LS Engine Parts Interchange 1997-2020

Mix and match parts for your LS engine to maximize power on a budget!

With its debut in 1997, the General Motors LS-series engine arguably became the most popular V-8 engine in the world. It was first offered in Corvettes and then migrated to the entire General Motors lineup (where V-8s were offered), and millions have been manufactured. These engines are compact, powerful, and abundantly available through salvage yards and crate-engine programs. Due to being manufactured for more than 20 years, many versions of the LS-engine platform exist, including more than 30 variants. Many parts are interchangeable, but some are not.

In LS Engine Parts Interchange: 1997–2020, veteran LS-engine authors Joseph Potak and Jefferson Bryant present a wealth of knowledge regarding which parts work well together and which parts do not. Parts that are covered include engine blocks, rotating assemblies, cylinder heads, camshafts and the valvetrain, oiling systems, intake manifolds, electronic engine controls, and more.

Which cam works best for your application? Perhaps you are interested in building a stroker with factory parts. Can you retrofit the free-flowing Gen IV heads onto a Gen III block? This book covers each of these topics. If you would like to extract more horsepower using all factory parts, if you want to plan for a swap, or if you simply want to know more about the entire LS engine family, this book is a vital resource.

Joseph Potak is a performance consultant, ASE Certified Master Technician, and automotive writer and enthusiast. He has been elbow deep with the LS-Series of engines for the better part of the past two decades, building performance-enhanced vehicles, testing engines on dynamometers, and constantly looking to push the performance envelope further every day via R & D projects. He is well known for his long tenure at Texas Speed and Performance and as a veteran moderator on LS1tech.com forums.

A lifelong car guy, Jefferson Bryant has been working on cars since the tender age of 16 when he bought a 1978 Pontiac Firebird. As a hands-on tech writer, he has performed many GM LS engine swaps in his own shop. His work has appeared in the country’s top automotive magazines, including Hot Rod, Car Craft, and Rod & Custom. Bryant has authored Swap LS Engines into Chevelles & GM A-Bodies, How to Swap GM LS-Series Engines into Almost Anything, and several other books.
