Edelbrock Pro Flo 4 EFI System Seq Port SBC 1986 & Earlier 675 Max HP 42lb/hr

Starting with its sequential port design, the Edelbrock Pro-Flo 4 EFI system for 1986 and earlier Small-Block Chevy engines places a fuel injector in each intake runner. This setup ensures excellent fuel atomization and consistent delivery to every cylinder, a key factor for maximizing performance in engines up to 675 horsepower. The system includes a high-performance Super Victor single-plane intake manifold, pre-assembled with fuel rails, a 4150-flange throttle body, and 42 lb/hr injectors capable of supporting that power level. This multi-fit system is designed for a wide range of classic Chevrolet, GMC, Buick, and other vehicles from the early 80s, offering a significant upgrade over carbureted setups.

At the heart of the Pro-Flo 4 is a new, compact ECU with a faster processor and a waterproof design. It connects wirelessly via an upgraded Bluetooth chip for a more reliable link to the free Edelbrock E-Tuner 4 app, available for Android and iOS devices. This app simplifies setup with a wizard and allows for advanced tuning of air-fuel ratios, ignition timing, idle speed, and more, all without needing a laptop. The system comes with 80 dyno-developed base calibrations, and the ECU's self-learning capability continually adjusts the tune for optimal performance based on real-world engine conditions. The kit includes all necessary sensors and a fully terminated, labeled harness for a straightforward installation.

This comprehensive kit is a solid choice for enthusiasts looking to modernize their classic Chevy V8. It includes the intake manifold, throttle body, injectors, fuel rails, ECU, sensors, and wiring harness. For those without a compatible smartphone or tablet, Edelbrock also offers kits that include a 7-inch Android tablet with the E-Tuner 4 app pre-installed, making the tuning process even more accessible.
