Description

Description

Overview:

This BluePrint Engine, configuration is a finely tuned symphony of power and precision, delivering a robust 600 horsepower and 530 ft. lbs. of torque. At its foundation lies BluePrint Engines’ high-strength cast iron LSX-style block, built to handle serious performance demands. Inside, forged pistons and a forged crank ensure durability and strength under high RPMs, while the hydraulic roller cam and LS3 aluminum heads optimize airflow and valve timing for maximum efficiency. With a compression ratio of 11:1, the engine strikes a balance between raw power and responsive throttle. The LS3 fabricated intake manifold and fuel rail system provides a sleek, high-flow path for fuel delivery, complemented by a modern drive-by-wire throttle body for precise control. Managing it all is the Holley Terminator X Max, offering advanced tuning and seamless integration for street or track dominance. This setup isn’t just built to run—it’s built to roar.
