Edelbrock Pro Flo 4 EFI System Seq Port SBC 1986 & Earlier 625 Max HP 35lb/hr Satin Finish

If you're looking to upgrade your classic Small-Block Chevy from 1986 or earlier to modern electronic fuel injection, the Edelbrock Pro-Flo 4 EFI system is a comprehensive solution. This kit replaces your carburetor and intake manifold with a complete EFI setup designed for improved performance and drivability. It's built to handle up to 550 horsepower with its included 35 Lb/hr injectors and 58 psi fuel pressure capability.

This system includes a traditional 4150-style single plane intake manifold with a clean satin finish. A key component is the updated ECU, which is smaller, waterproof, and features a faster processor and more reliable Bluetooth for seamless connection to the E-Tuner 4 app. This app, available for Android and iOS devices, allows for wireless tuning and self-learning adjustments to optimize your engine's air-fuel ratio, ignition timing, and idle speed. You get control over essential parameters like acceleration fuel enrichment, cooling fan operation, and a rev limiter, all while maintaining the user-friendly simplicity Edelbrock is known for. The system also comes with a plug-and-play distributor and a high-quality, clearly labeled wiring harness made in the USA to simplify installation.

The Pro-Flo 4 EFI system is designed to fit a wide range of vehicles from the 1980s, including popular models like the Chevrolet C10, Camaro, and GMC C1500. It does not require a laptop for tuning, relying instead on the intuitive E-Tuner 4 app and its pre-loaded, dyno-developed calibrations. Multiple dash display options are available within the app to monitor your engine's vital signs directly from your smartphone or tablet.
