The Edelbrock Pro-Flo 4 EFI Kit for 1970-1991 AMC 304, 360, 390, 401 CID engines is a fully sequential multi-port injection system designed with a fuel injector strategically positioned in each runner of the intake manifold to deliver the best fuel atomization and most even distribution to each cylinder. This system features the high-performance Victor Jr.-style single-plane intake manifold that comes preassembled with high-flow injectors, fuel rails, and 4150-flange throttle body. All supporting sensors and the distributor, wire harnesses, and ECU are included. 

The Victor manifold is designed with a larger cross-sectional area in the plenum and larger runners for high-horsepower and/or large cubic-inch applications. This kit uses 35 lb/hr injectors and is rated for 550 horsepower at 58 PSI of fuel pressure. Calibration of the Pro-Flo 4 is a simple process with a Setup Wizard providing guidance through the E-Tuner's initial programming. Once provided with basic information such as type of engine, cubic inches, firing order, and cam profile, the E-Tuner then selects the most appropriate base calibration. Once the base calibration is set, the self-learning E-Tuner takes over to continually maximize the fuel map for your specific engine configuration, even compensating for changes in altitude and weather.

The E-Tuner provides more advanced tuning options that allow precise control over cold starts and acceleration while retaining the simplicity that Pro-Flo systems are known for. No laptop tuning is required.The exclusive Edelbrock E-Tuner 4 app is Free and Available for Android and IOS based smart phone or tablet
