    Overview:

    The BluePrint ever popular GM LS-Compatible 376 c.i. performance crate engine delivers a dyno-tested 510 horsepower and 440 ft. lbs. of torque, right out of the box. This engine comes equipped with BluePrint’s fully calibrated multi-port fuel injection system—engineered for precision and reliability. The included ECU and complete wiring harness make installation straightforward and stress-free and has been rigorously tested over the course of a year in both on-road and off-road environments, under a wide range of temperatures and conditions. The result? A finely tuned, fully optimized calibration that maximizes the power and drivability of this 376 c.i. powerhouse—far surpassing the performance of typical self-learn EFI systems. The BluePrint ECU manages both ignition timing and fuel delivery and supports seamless self-learn functionality as you add bolt-on upgrades like headers, camshafts, or performance exhaust systems. With just three simple connections—Main Battery, switched 12V Ignition, and Fuel Pump—you’ll be up and running in no time.
