Universal Fit, 555 cu. in. Engine Displacement, Long Block Crate Engine Type
**$175 shipping included in price
The Edelbrock/Musi 555 Pro-Flo 4 XT is the most powerful package in our line and features the Pro-Flo 4 XT electronic fuel injection. The Pro-Flo 4 XT EFI system consists of a front mount 90mm throttle body design manifold with a large plenum and tapered runners that deliver more horsepower and torque than a traditional single-plane intake manifold. The system also includes fuel injectors, fuel rails, fuel pump, throttle body, electronic engine control unit (ECU) and 7" Android tablet with pre-loaded E-Tuner app and calibrations.
Like the Pro-Flo 4 single-plane application, this engine is ready to run right out of the crate with pre-loaded calibrations. The E-Tuner app uses a Bluetooth wireless connection to communicate with the ECU’s self-learning capability to continually adjust the calibration to get the maximum performance of your engine.
