The ZZ454/440 base engine is a fully assembled long block. This engine is assembled using brand new, premium
quality components. The ZZ454/440 engine is manufactured on current production tooling; consequently you may
encounter dissimilarities between the ZZ454/440 engine assembly and previous versions of the big block V8. In
general, items such as motor mounts, accessory drives, exhaust manifolds, etc. can be transferred to a ZZ454/440
engine when installed in a vehicle originally equipped with a big block V8 engine. However, as noted in the following
sections, there may be significant differences in the water pump, torsional damper, etc., between a ZZ454/440 engine
and an older big block V8 engine. These differences may require modifications or additional components not included
with the ZZ454/440 engine. When installing the ZZ454/440 engine in a vehicle not originally equipped with a big
block V8, it may be necessary to adapt or fabricate various components for the cooling, fuel, electrical, and exhaust
systems. Due to the wide variety of vehicles in which a ZZ454/440 engine can be installed, some procedures and
recommendations may not apply to specific applications.
It is not the intent of these specifications to replace the comprehensive and detailed service practices explained in the
GM 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 ZZ454/440 engine in any vehicle.
Wear eye protection and appropriate protective clothing. Support the vehicle securely with jackstands when working
under or around it. 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.
