INTRODUCTION
Thank you for selecting the Edelbrock Pro-Flo Fuel Injection System. These Multi-Point Fuel Injection Systems have been designed
for 1967-1969 290-390 cid (#3530), and 1970-1991 304-401cid (#3531) AMC V8 engines, and are designed to provide excellent
performance, fuel economy, and maintenance-free operation. Installation of the Edelbrock/ Pro-Flo 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 system.
Calibration Chips:
Important Notice: The Edelbrock Pro-Flo Fuel Injection System is shipped without the computer chip. The chip is
necessary to operate the ECU. If the cam is any brand other than Edelbrock, check with manufacturer for compatibility with EFI.
Complete the Chip Information Card and return to Edelbrock. We will send the computer chip within the continental U.S., free of
charge via UPS second day air. Orders outside of the continental U.S. will be shipped via the best method at the same costs as
continental UPS second day air. If requested, customers may pay for expedited shipping by providing a current Visa or Master Card.
The chip installs into the System Computer in minutes. Additional chips are available for a nominal charge if you decide to change
your cam. Edelbrock has chips for assorted cam profiles.
If you have any questions, do not hesitate to call our
