Performance Deluxe ZZ572/620 Manual De Instrucciones página 2

Legal and Emissions Information
This publication is intended to provide information about the ZZ572 engine and related components. This manual also
describes procedures and modifications that may be useful during the installation of a ZZ572 engine. It is not intended
to replace the comprehensive service manuals and parts catalogs which cover Chevrolet engines and components.
Rather, it is designed to provide supplemental information in areas of interest to "do-it-yourself" enthusiasts and
mechanics.
This 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.
Many of the parts described or listed in this manual are merchandised for off-highway application only, and are tagged
with the "Special Parts Notice" reproduced here:
Special Parts Notice

impair your vehicle's emission control performance or be uncertified under current Motor Vehicle Safety Standards, it
should not be installed in a vehicle used on any street or highway. Additionally, any such application could adversely
affect the warranty coverage of such an on-street or highway vehicle.
