Chevrolet Big Block Oval-Port Pro-Flo 4 4150 EFI System, 60-lb/hr Injectors by Edelbrock®

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

This Edelbrock® Pro-Flo 4 4150 system combines an assembled intake manifold, dual aluminum fuel rails and eight 60-lb/hr injectors for Chevrolet Big Block Oval-Port cylinder heads. The 4150-style throttle-body layout retains a conventional four-barrel induction profile. 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.
