INTRODUCTION
Thank you for selecting the Edelbrock Pro-Flo Fuel Injection System. This Multi-Point Fuel Injection System has been designed for 454 c.i.d. big-
block Chevrolet engines, and is 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.
If you have any questions, do not hesitate to call our
