Turn Key Engine supply was founded with the intent of providing both the
professional and amateur installer with the most comprehensive and flexible engine
packages possible. The combination of state of the art engines and our extensive research
results in packages that ensure maximum performance, reliability and ease of installation.
We assemble engines with new OEM components where applicable, we may modify and/
or interchange components as necessary to meet specific application requirements.

Every effort has been made to ensure we provide a TURN KEY package, as
applications will vary widely we can not guarantee that this package includes everything
you will need for your installation. We will be happy to assist you with your specific
application.

As every application is different it would be impossible to provide all the
information necessary to complete installations for every application. This document is
intended as a guide and does not provide a step-by-step explanation of what is required to
successfully install the engine. Every effort has been made to accurately summarize the
information necessary for you to install and maintain your TURN KEY engine. It is
assumed that the installer has the knowledge and expertise to successfully install the
engine.

We highly recommend that you consult an OEM Service Manual, follow
generally accepted safety practices and seek professional assistance when necessary.

The General Motors family of Gen 3 V8 engines is very similar and often uses
components that are identical or interchangeable. Turnkey Engine Supply has invested in
considerable research and development to ensure the engine package you receive will
offer the maximum performance and reliability for your application. In some cases the
actual components (example: sensors) and their different configurations (example: belts)
are different from those installed during manufacturing. This is done to enhance
performance and reliability, when applicable we utilize new General Motors components.
In some cases it is necessary for us to utilize custom components or modified components
to ensure an optimum “Turn-Key” package (example: ECM and Wiring Harness). In the
event you need to replace components we recommend you contact our technical
department to ensure proper components are used.

Emissions laws vary from state to state, you MUST understand and adhere to the
applicable laws. In some cases this package may only be legal for off road applications.

These are high performance products and Turn Key Engine Supply assumes zero
liability as a result of improper use or inexperience of use.

OIL

The LS engine requires oil that meets or exceeds the American Petroleum
Institute standards for SL. 10W-30 is what we recommend; we do not recommend the use
of synthetic oil until the completion of break in procedure and 15 hours of normal
operation time. We recommend for off road use changing your oil for every 20 hours of
operating time.

Oil Pressure
A sending unit bung is provided to be installed behind the intake manifold above

the bell housing. You can also drill and tap by the oil filter if this bung in not accessible.
