      INTRODUCTION

      A longtime cliché of the automotive world is the phrase “they don’t build ’em like they used to.” When it comes to the performance capability of the General Motors Gen III/Gen IV engines (commonly known as “LS” engines), that old adage couldn’t be truer—but not in the traditional sense.

      The LS engines aren’t built like the old small-blocks, and that’s a good thing. They’ve proven to be very durable and, with their exceptional airflow capabilities, they are capable of tremendous power with comparatively little work. Add a supercharger or turbo system to one of these compact powerhouses and the dyno numbers go through the roof.
