INTRODUCTION
Thank you for selecting the Edelbrock Pro-Flo XT Fuel Injection System. This Multi-Point Fuel Injection System has been designed for 350 c.i.d.
small-block Chevrolet engines, and is designed to provide excellent performance, fuel economy, and maintenance-free operation. Installation of
the Edelbrock Pro-Flo XT Fuel Injection System involves modifications to the fuel system, ignition system, induction system, and possibly the
valve train. Although there are steps that must take place before others, the modifications do not necessarily have to be performed in a particular
order. Each modification is described in a separate section in this manual. Please study these instructions carefully before beginning installation
of any part of the Pro-Flo XT system.
If you have any questions, do not hesitate to call our
