Overview:

The BluePrint 383 Small Block Chevy compatible performance crate engine is dyno tested at our factory with guaranteed power levels of 436 horsepower and 443 ft. lbs. of torque. The BluePrint designed and fully calibrated, multi-port fuel injection system comes complete with ECU and full Wiring Harness. This fully optimized EFI system has had over a year of extensive on-road, off-road testing under multiple temperature and road conditions. The optimized calibration is specifically tuned and optimized for this engine and goes well beyond the performance of current self-learn EFI systems on the market today. This BluePrint ECU is designed for hassle-free start up and continuous self-learn operation as you add bolt on parts like headers and exhaust. The ECU controls ignition timing and fuel and installs with 3 simple wired connections (Main Battery, Switched 12V Ignition Wire and Fuel Pump).

The Included BluePrint Engines MPFI controller package contains a fully tested, calibrated, locked ECU, optimized for this specific engine. This package has undergone extensive testing for performance, reliability and the safety of you and your engine.
