Your Rating


The Edelbrock Pro-Flo 4 EFI Kit #35780 for the Small-Block Chevy engine with Vortec/E-Tec cylinder heads is a fully sequential multi-port injection system designed with a fuel injector strategically positioned in each runner of the intake manifold to deliver the best fuel atomization and most even distribution to each cylinder. This system features the high-performance Victor-style single-plane intake manifold that comes preassembled with high-flow 29 lb/hr injectors, fuel rails and 4150-flange throttle body. The Pro-Flo 4 EFI #35780 is compatible with factory-style cylinder heads or Edelbrock Performer and Performer RPM Cylinder heads. Also included is a distributor designed to work specifically with Pro-Flo 4 providing fully sequential port injection and infinite control over ignition and fuel events. This system is rated for 450 horsepower at 58 PSI with all supporting sensors, ECU, wire harnesses and 7-inch Android tablet for a streamlined installation. Key Pro-Flo 4 features are Self-Learning Fuel Map Technology, Wide-Band O2 Closed Loop Mixture Control and an ECU with advanced processor technology and Bluetooth connectivity. E-Tuner Android Software includes a Setup Wizard to simplify installation and provides fuel and spark adjustability for complete control over the system. Pro-Flo 4 EFI requires no laptop tuning. Minimal setup and tuning adjustments are required with base calibrations provided in the software. The ECU is self-learning and will continually adjust the fuel injection calibration for maximum performance by maintaining a specified target air-fuel ratio as you drive. The E-Tuner Software provides the ability to fine-tune air-fuel ratios, ignition curve, idle speed, acceleration fuel, fans, rev-limiter and more. Multiple displays let you monitor engine performance in real-time from inside or outside of the vehicle while retaining the simplicity that Pro-Flo 4 systems are known for.
