Edelbrock Pro-Flo 4 EFI System, Small-Block Chevy, Vortec/E-Tec Heads, 450 HP, Satin

Sequential multi-port EFI system with satin aluminum intake, self-learning ECU and 29 lb/hr injectors

Convert your small-block Chevrolet engine equipped with Vortec or Edelbrock E-Tec cylinder heads to electronic fuel injection with the Edelbrock Pro-Flo 4 EFI system. Featuring a satin-finish aluminum single-plane intake manifold, this fully sequential multi-port injection system positions eight 29 lb/hr fuel injectors near the cylinder head intake ports for precise fuel metering and distribution. Rated for engines producing up to 450 horsepower at 58 PSI fuel pressure, the system incorporates a traditional 4150-style four-barrel throttle body with an airflow capacity of up to 1,000 CFM. The intake manifold is designed specifically for compatible Vortec and E-Tec cylinder head configurations. Each system includes the assembled intake manifold, throttle body, fuel rails, injectors, electronic control unit (ECU), dedicated distributor, wiring harnesses and supporting engine sensors. Edelbrock's self-learning fuel management system communicates wirelessly through Bluetooth with the E-Tuner 4 application, allowing initial setup, engine monitoring and adjustments to fuel delivery, ignition timing, idle speed and other operating parameters using a compatible smartphone or tablet. Dyno-developed base calibrations simplify initial startup, while the ECU continuously adjusts fuel delivery to accommodate changing engine conditions. A separate high-pressure EFI fuel delivery system is required for installation.
