Overview:

This LS3-based engine build is a masterclass in modern performance and reliability, delivering a robust 525 horsepower and 460 ft. lbs. of torque. With a 10.7:1 compression ratio, it’s engineered for high-output efficiency and streetable power. At its heart are BluePrint Engines’ premium components, including LS3 aluminum heads, a hydraulic roller cam, hypereutectic pistons, and a nodular iron crankshaft—each chosen for strength and precision. Fuel and air management are handled by the Holley Terminator X Max system, paired with a fabricated aluminum intake manifold, high-flow injectors, and a matching fuel rail kit. The LS Swap oil pan ensures proper fitment across platforms, while the drive-by-wire throttle body adds cutting-edge responsiveness. Tying it all together is a black pulley kit featuring an LS2-style water pump, a high-output 140-amp alternator, a compact peanut-style A/C compressor, and a Type II power steering pump with remote reservoir—delivering both form and function in a sleek, performance-ready package.
