Edelbrock Pro Flo 4 Fuel Inject Kit XT Seq Port SBC 429/460 1986 625 Max HP 35 LbHr Injectors Black

If you're looking to upgrade your 1986 or earlier Small-Block Chevrolet engine to modern electronic fuel injection, the Edelbrock Pro-Flo 4 XT EFI System is a complete, bolt-on solution. This kit replaces your carburetor and intake manifold with a sophisticated EFI setup designed to improve how your engine runs, especially in varying conditions. It's a comprehensive package that brings your classic engine into the 21st century with improved drivability and performance.

This system features a black powder-coated XT intake manifold with a large plenum and long, tapered runners, which Edelbrock has pre-assembled with high-flow 35 lb/hr injectors, fuel rails, and a 90mm throttle body. It's rated to support up to 625 horsepower. The kit includes all necessary sensors, a wide-band O2 sensor, and wire harnesses, along with a single-connection distributor that works with the Pro-Flo 4 for fully sequential port injection. A key advancement is the self-calibrating fuel map technology and wide-band O2 closed-loop mixture control, managed by a new low-profile ECU with an upgraded processor and Bluetooth for reliable connection to the E-Tuner app. This app, available for Android and iOS devices, guides you through setup and allows for detailed tuning of fuel and spark. The system is designed to be self-learning, continuously adjusting the fuel injection calibration for optimal performance as you drive, meaning you don't need a laptop for basic operation.

The Pro-Flo 4 XT EFI System comes with an Android-based tablet preloaded with the E-Tuner app, simplifying the initial setup and ongoing adjustments. You can fine-tune air-fuel ratios, ignition curves, idle speed, and more, all displayed in real-time on the tablet. This system fits a wide range of vehicles, including popular models like the Chevrolet Bel Air, Camaro, and C10 Pickup from various years. It’s a well-built system that aims to provide a significant improvement in engine response and fuel efficiency.
