This publication provides general information on components and procedures which may be useful when installing or servicing your crate engine.
Please read this entire publication before starting work.
These crate engines are assembled using brand new, premium quality components. They are based off of the General Motors (GM) Generation IV LS3
Series architecture, and utilize such modern technologies as fuel injection, individual ignition coil per cylinder, and electronic throttle control. Due to
the wide range of small block applications, if you are retrofitting a previous small block application, you may encounter installation differences
between your crate engine assemblies and the previous version. These differences may require modifications or additional components not included
with the engine, including cooling, fuel, electrical, and exhaust systems.
Some fabrication work may be required.
The LS376/480, LS376/525 crate engines require an engine control system and harness which are available from your Chevrolet
Performance Parts dealer. Check with your dealer or on chevroletperformance.com for the control system packages that are currently
available. Generally, the fuel system requirement is 60 psi (400 kPa) constant fuel pressure, but check the information included in
your engine control system for the actual pressure requirement.
User Note: The Chevrolet Performance Parts LS376/480 crate engine comes equipped with the LS Hot Cam and the LS376/525
comes with the LS ASA cam both of which are aggressive high-performance camshafts that may cause slight surging below 2500
rpm under light load. This should be considered a normal functioning occurrence given the aggressive nature of these camshafts.
This surging can be avoided by increasing either the rpm or throttle of the engine at the same given velocity.
Under full throttle usage, you should not experience any surging when using a Chevrolet performance engine control system. 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 crate engine in any vehicle. Wear eye protection
and appropriate protective clothing. When working under or around the vehicle support it securely with jack stands. 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.
