This publication provides general information on components and procedures which may be useful when
installing or servicing a 350HO Deluxe 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, 350HO
Deluxe Engine specifications, additional parts that you may need to purchase, torque specifications, and a
service parts list.
The 350HO Deluxe 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 350HO Deluxe Engine
can be installed, some procedures and recommendations may not apply to specific applications.
The 350HO Deluxe Engine is manufactured on current production tooling; consequently you may encounter
dissimilarities between the 350HO Deluxe 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
350HO Deluxe 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 350HO Deluxe Engine and an older
small block V-8 engine. These differences may require modifications or additional components not included
with the 350HO Deluxe Engine. When installing a 350HO Deluxe 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 ex-
plained in the GM service manuals.
For information about warranty coverage, please contact your local GM Performance Parts dealer.
Observe all safety precautions and warnings in the service manuals when installing a 350HO Deluxe 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 conver-
sion safely, this work should be done by a professional.
