GM (General Motors) Sport Compact Performance Build Book

Taken from Introduction: This handbook describes parts and procedures used to prepare ECOTEC Race Engines used by GM Racing in professional sport compact drag racing, as well as engine, transmission, and chassis modifications designed for, sportsman-level drag racers and road racers.

This handbook is intended to be used by experienced and knowledgeable race engine and chassis builders. It does not cover basic engine blueprinting and assembly procedures, since it is assumed that the reader is already familiar with machining, measuring, and inspecting the components. Some of the procedures described require specialized tools and skills. If you do not have the appropriate training and equipment to perform these modifications safely, this work should be performed by other professionals.

There are of course, many other possible combinations of components and additional modifications that may produce equal or superior results. However, by using the combination of parts and procedures described in this handbook, an experienced engine builder can build a competitive and reliable ECOTEC Race Engine.

It is not the intent of these specifications to replace the comprehensive and detailed service practices explained in the GM service manuals
