Description

This engine build is a masterclass in modern muscle, pushing out a commanding 600 horsepower and 530 ft. lbs. of torque with a crisp 11:1 compression ratio. At its heart is BluePrint Engines’ high-strength cast iron LSX-style block, fortified with forged pistons and a forged crank for uncompromising durability and high-RPM stability. The LS3 aluminum heads and hydraulic roller cam work in harmony to maximize airflow and valve timing, delivering smooth, responsive power across the rev range. Fuel and air are fed through a sleek LS3 fabricated intake manifold and fuel rail system, with a drive-by-wire throttle body ensuring precise control. The Holley Terminator X Max system brings advanced engine management to the table, making tuning and diagnostics seamless. A black pulley kit adds both function and flair, 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. This setup isn’t just built to perform—it’s built to impress, whether you're carving corners or cruising the boulevard.
