Edelbrock Pro Flo 4 EFI System Seq Port Chrysler Gen II Hemi 426-572 950 Max HP 60lb/hr Satin Finish

If you're looking to bring your classic Chrysler Gen II Hemi engine into the modern age of fuel delivery, the Edelbrock Pro-Flo 4 Dual-Quad EFI System is a serious consideration. This system is designed for 1964-71 Mopar Gen II 426-572 HEMI engines, especially those built for performance and operating in the 2,500-6,500+ RPM range. It replaces your carburetor setup with a sophisticated electronic fuel injection system that offers improved drivability and performance.

What sets this system apart is its dual-plane Air-Gap manifold topped with two square-bore 4150-style throttle bodies, designed to fit directly onto vehicles with a shaker hood. While compatible with factory-style cylinder heads, it's optimized for Victor Jr. HEMI heads for maximum performance. The system comes pre-assembled with 60 lb/hr injectors and fuel rails, along with a unique single-connection distributor that works with the Pro-Flo 4 ECU for fully sequential-port injection and precise control over both fuel and ignition events. This means your engine gets exactly the fuel it needs, when it needs it, for consistent power delivery under all driving conditions.

The real magic of the Pro-Flo 4 system is its Self-Calibrating Fuel Map Technology. It features Wide-Band O2 Closed Loop Mixture Control and a new, low-profile ECU with an upgraded processor and Bluetooth chip. This allows it to connect reliably to the included 7-inch Android tablet running the E-Tuner app. You don't need a laptop to tune this system; the Setup Wizard guides you through installation, and the ECU is self-learning, continually adjusting the fuel injection calibration to achieve optimal air-fuel ratios as you drive. You can fine-tune air-fuel ratios, ignition curves, idle speed, and more directly from the tablet, monitoring engine performance in real-time while enjoying the simplicity that Edelbrock is known for. This system is rated for up to 825 horsepower at 43 PSI and includes all necessary supporting sensors, ECU, and wire harnesses for a streamlined installation.
