Overview:

This powerhouse of an engine build is a testament to precision engineering and raw performance. Delivering a formidable 585 horsepower and 520 ft. lbs. of torque, it’s driven by a BluePrint Engines LSX-style high-strength cast iron block, paired with forged crank and pistons for uncompromising durability. The 11:1 compression ratio ensures optimal combustion efficiency, while LS3 aluminum heads and a hydraulic roller cam (featured twice for emphasis on valvetrain performance) bring refined airflow and aggressive cam timing. Feeding this beast is a drive-by-wire throttle body and LS3 cast aluminum intake manifold, supported by a complete injector and fuel rail kit for consistent fuel delivery. The LS swap oil pan, water pump, and gas pedal round out the essentials, while the Holley Terminator X Max ECU provides cutting-edge engine management. A black pulley kit featuring an LS2-style water pump, 140-amp alternator, peanut-style A/C compressor, and Type II power steering pump with remote reservoir ensures accessory systems run smoothly and reliably. Altogether, this setup blends brute force with modern control, making it ideal for high-performance street applications.
