Edelbrock Pro Flo 4 EFI System Seq Port BBC Rect Port 625 Max HP 35lb/hr Satin Finish

Starting with the 35 Lb/Hr injectors, this Edelbrock Pro-Flo 4 EFI system is built for Big-Block Chevy Rectangle Port engines. These injectors are rated to support up to 625 horsepower with 58 p.s.i. of fuel pressure, giving you a solid foundation for significant power gains. The system includes a traditional 4150-style single plane intake manifold with a satin finish, designed to integrate seamlessly with your engine. This is a multi-fit system designed for a wide range of Chevrolet vehicles, including models like the 1965-1975 Bel Air, 1967-1972 Camaro, and 1965-1974 Corvette.

At the heart of the Pro-Flo 4 is a completely new ECU. It boasts a faster processor, a waterproof design, and is half the depth of previous units, making installation easier. The upgraded Bluetooth chip ensures a faster, more reliable connection without dropouts, crucial for the system's self-learning capabilities. This ECU offers advanced tuning control over air-fuel ratios, ignition curves, idle speed, acceleration fuel, coolant fans, and rev limiters, while still maintaining the user-friendly simplicity Edelbrock is known for. The system is managed through the exclusive E-Tuner 4 app, which uses dyno-developed base calibrations. This app connects wirelessly via Bluetooth to your Android or iOS smartphone or tablet, allowing the ECU to continually adjust the calibration for maximum performance. The app features a simple setup wizard and multiple dash displays to monitor engine vitals, eliminating the need for laptop tuning.

Installation is made more straightforward with a plug-and-play single connection distributor and a high-quality, fully terminated harness made in the USA, featuring clearly labeled connections. Edelbrock also offers kits that include a 7-inch Android tablet with the E-Tuner 4 app pre-installed, for those who prefer a dedicated device. This system is a comprehensive upgrade for enthusiasts looking to bring modern fuel injection technology to their classic Big-Block Chevy.
