It is also intended as a guide for rebuilding specifications.  \nRefer to service manual for comprehensive and detailed service practices. Observe all safety precautions and warnings in the service manual for installation in the vehicle. Wear eye protection and appropriate protective clothing. When working under or around the vehicle support it securely with jack-stands. Use only the proper tools. Exercise extreme caution when working with flammable, corrosive, and hazardous liquids and materials. Some procedures require special equipment and skills. If you do not have the appropriate training, expertise, and tools to perform any part of the installation then contact a professional.  \nLegal Information  \nThis publication is intended to provide information about your circle track engine and related components. The publication also describes procedures and modifications that may be useful during the installation. It is not intended to replace the comprehensive service manuals or parts catalogs which cover General Motors engines and components. Rather, it is designed to provide supplemental information in areas of interest and to “do-it-yourself” enthusiasts and mechanics.  \nThis publication pertains to engines and vehicles which are used off the public highways except where specifically noted otherwise. Federal law restricts the removal of any part of a federally required emission control system on motor vehicles. Further, many states have enacted laws which prohibit tampering with or modifying any required emission or noise control system. Vehicles which are not operated on public highways are generally exempt from most regulations. As are some special interest and pre-emission vehicles. The reader is strongly urged to check all applicable local and state laws.  \nGM has a long history of providing the engine of choice for circle track racing. The introduction of the small block Chevy in 1955 started it all. Production parts were durable, and the engines were plentiful.
