PREFACE
This document will assist the reader in the application of the 4.3L V6 90 Degree Engine to the vehicle.
It gives an overview of the engine, its features, as well as focus on the systems, subsystems and
attachments that interface between the engine and the vehicle.
The performance of the 4.3L V6 90 Degree Engine is dependent on the design and processing of the
interface systems and their components.
