BluePrint Engines Pro Series Chevy LS 427 C.I.D. 600 HP EFI Base Dressed Long Block Crate Engines

BluePrint Engines Pro Series Chevy LS 427 c.i.d. 600 hp Holley Terminator X EFI base dressed engines are a finely tuned symphony of power and precision, delivering a robust 600 hp and 530 lb.-ft. of torque, with a crisp 11:1 compression ratio.

At its foundation lies BluePrint's 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.

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.
