Overview:

The BluePrint 400 Small Block Chevy compatible performance crate engines are dyno tested at our factory with guaranteed power levels of 500 horsepower and 500 ft. lbs. of torque. The BluePrint designed, multi-port fuel injection system, complete with ECU and full Wiring Harness, has had extensive calibration and development work in creating this specifically tuned and optimized engine that goes well beyond the performance of self-learn EFI systems on the market today. This BluePrint ECU is designed for hassle-free start up and operation. The ECU controls ignition timing and fuel and installs with 3 simple wired connections (Main Battery, Switched 12V Ignition Wire and Fuel Pump).
