This publication provides general information on components and procedures which may be useful when installing or servicing
a 350/290 HP 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, 350/290 HP engine
specifications, additional parts that you may need to purchase, torque specifications, and a service parts list.
The 350/290 HP engine incorporates modern technology in a package that can be installed in most applications where
265-400ci small block Chevrolet V-8s were originally used. This complete engine is assembled using brand new, premium
quality components. Due to the wide variety of vehicles in which a 350/290 HP engine can be installed, some procedures and
recommendations may not apply to specific applications.
The 350/290 HP engine is internally balanced and requires no balance weights on either the flywheel/flexplate or the harmonic
balancer. A non-Vortech design intake manifold must also be used. When using the 350/290 HP engine as a replacement for
an original equipment engine, the performance intent of this engine should be considered. The torque curve is higher and
consequently may require a torque converter with a higher stall speed on automatic transmission equipped vehicles. Consult
with a reputable torque converter manufacturer for assistance in selecting the correct torque converter for your application.
The 350/290 HP engine is manufactured on current production tooling; consequently you may encounter dissimilarities between
the 350/290 HP 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 350/290 HP 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 350/290
HP engine and an older small block V-8 engine. These differences may require modifications or additional components not
included with the 350/290 HP engine. When installing a 350/290 HP 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 Chevrolet
service manuals.
For information about warranty coverage, please contact your local Chevrolet Performance dealer.
Observe all safety precautions and warnings in the service manuals when installing a 350/290 HP 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.
