Chevrolet Big Block Rectangular-Port Pro-Flo 4 XT EFI System, 35-lb/hr Injectors by Edelbrock®

An assembled induction system and labeled harnesses combine self-learning EFI with adjustable tuning.

This Edelbrock® Pro-Flo 4 XT system combines an assembled intake manifold, dual aluminum fuel rails and eight 35-lb/hr injectors for Chevrolet Big Block Rectangular-Port cylinder heads. A front-mounted 90mm throttle body and throttle/transmission kickdown bracket are included. The ECU uses a Bluetooth connection to the free E-Tuner 4 app for Android or iOS devices. Self-learning fuel control works alongside adjustments for air/fuel targets, ignition curve, idle speed, acceleration fuel, cooling fans and rev limit, with real-time monitoring. Clearly labeled, pre-terminated main-engine and injector/sensor harnesses simplify wiring. The package supplies an oxygen sensor, fuel-pressure sensor, throttle-position sensor, idle-air control, MAP sensor, gaskets and installation hardware. A USA-made Pro-Flo distributor with a single plug-in connection and a coolant-temperature sensor are included. The manifold finish is satin or black.
