The new Pro-Flo 4 EFI System #35680 for Ford 429/460 engines is an advanced sequential-port electronic fuel injection for the 385-series big-blocks manufactured from 1968 through 1997. This EFI is a direct bolt on and incorporates a single-plane Victor-style intake manifold with a square-bore 4150-style throttle body. The Pro-Flo 4 EFI #35680 is compatible with factory-style cylinder heads but optimized for use with Edelbrock Performer and Victor Jr. heads. The Pro-Flo 4 manifold comes preassembled and ready to run with throttle body, 42 lb/hr injectors and fuel rails. Also included is a single-connection distributor designed to work specifically with Pro-Flo 4 providing fully sequential direct-port injection and infinite control over ignition and fuel events under all conditions. This system is rated for 625 horsepower at 43 PSI with all supporting sensors, ECU, wire harnesses and 7-inch Android tablet included for a streamlined installation. Key Pro-Flo 4 advancements are its Self-Calibrating Fuel Map Technology, Wide-Band O2 Closed Loop Mixture Control, and new low-profile ECU with faster processor and upgraded Bluetooth chip for reliable connectivity with the E-Tuner app that comes preinstalled on the tablet. The E-Tuner includes a Setup Wizard to guide you through setup and provides fuel and spark adjustability for complete control over the system. Pro-Flo 4 EFI requires no laptop tuning. Minimal setup and tuning adjustments are required with base calibrations provided in the software. The ECU is self-learning and will continually adjust the fuel injection calibration for maximum performance by maintaining a specified target air-fuel ratio as you drive. The E-Tuner provides the ability to fine-tune air-fuel ratios, ignition curve, idle speed, acceleration fuel, fans, rev-limiter and more. Multiple displays let you monitor engine performance in real-time from inside or outside of the vehicle while retaining the simplicity that Pro-Flo 4 systems are known for.
