This publication provides general information on components and procedures which may be useful when installing or servicing
a ZZ4 engine. Please read this entire publication before starting work. Also, please verify that all of the components listed in the
Package Contents section below were shipped in the kit.
The information below is divided into the following sections: package contents, component information, ZZ4 engine
specifications, additional parts that you may need to purchase, torque specifications, and a service parts list.
The ZZ4 engine incorporates modern technology in a package that can be installed in applications where 265-400ci small block
Chevrolet V-8's were originally used. This complete engine is assembled using brand new, premium quality components. Due
to the wide variety of vehicles in which a ZZ4 engine can be installed, some procedures and recommendations may not apply to
specific applications.
The ZZ4 engine is manufactured on current production tooling; consequently you may encounter dissimilarities between the
ZZ4 engine assembly and previous versions of the small block V-8. In general, items such as motor mounts, accessory drives,
exhaust manifolds, etc. can be transferred to a ZZ4 when it is installed in a vehicle originally equipped with a small block V-8
engine. However, as noted in the following sections, there may be minor differences between a ZZ4 engine and an older small
block V-8 engine. These differences may require modifications or additional components not included with the ZZ4 engine.
When installing a ZZ4 engine in a vehicle not originally equipped with a small block V-8, it may be necessary to adapt or
fabricate various components for the cooling, fuel, electrical, and exhaust systems.
It is not the intent of these specifications to replace the comprehensive and detailed service practices explained in the factory
service manuals.
For information about warranty coverage, please contact your local Chevrolet Performance Parts dealer.
Observe all safety precautions and warnings in the service manuals when installing a ZZ4 engine in any vehicle. Wear eye
protection and appropriate protective clothing. When working under or around the vehicle support it securely with jackstands.
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 this conversion safely, this work should be done by a professional.
