Founded in 1993 CarTech, Inc has become one of the leading publishers of how-to automotive titles for the hardcore enthusiast. In 1995 CarTech purchased the S-A Design line of book from Larry Schreib and Larry Atherton who had published their first book in 1976 titled, The Chevrolet Racing Engine, by Bill Grumpy Jenkins. This single title gained wide recognition as “the bible” of high performance engine design and assembly.
CarTech has continued to expand on this tradition and now has over 300 titles available for the enthusiast, in a wide variety of formats – from print to digital to video. Today, our publishing efforts include our traditional performance “S-A Design” titles along with race histories, biographies of industry icons; in addition to a number series that further assist readers with their projects.
