Edelbrock Pro Flo 4 XT EFI System Seq Port BBC Rect Port Std Deck 775 Max HP 60lb/hr Black Finish

If you're looking to get the most out of your Big-Block Chevrolet engine, especially one built for serious power, upgrading to a modern electronic fuel injection system is a smart move. This Edelbrock Pro-Flo 4 XT EFI kit is designed for rectangular-port BBCs and offers a complete, bolt-on solution that brings your engine into the 21st century. It handles up to 825 horsepower with the included 60 lb/hr injectors, making it a solid choice for performance builds.

What sets this kit apart is how complete it is right out of the box. Edelbrock pre-assembles the XT intake manifold, which features a large plenum and long, tapered runners for improved airflow, along with the fuel rails, high-flow injectors, and a 90mm throttle body. It also includes all the necessary sensors, a wide-band O2 sensor for accurate air-fuel ratio monitoring, and a dedicated wire harness. The real magic happens with the included Android tablet running the E-Tuner app. This system features self-calibrating fuel map technology and wide-band O2 closed-loop mixture control, meaning it learns and adjusts as you drive to maintain optimal performance. The new, low-profile ECU has a faster processor and an upgraded Bluetooth chip for reliable connection to the E-Tuner app, which guides you through setup and offers extensive tuning capabilities for fuel, spark, idle speed, and more, all without needing a laptop.

This system is designed for a hassle-free installation, with a single-connection distributor that works specifically with the Pro-Flo 4 for fully sequential port injection. The E-Tuner app provides real-time engine monitoring and allows for fine-tuning of various parameters, giving you complete control over your engine's performance. While it offers advanced tuning options, it retains the simplicity that Pro-Flo systems are known for, making it accessible even if you're not a dedicated EFI tuner. This kit fits a wide range of Chevrolet vehicles from the mid-60s through the mid-90s, including popular models like the Impala, Chevelle, and C10 pickups.
