Overview:
BluePrint Motorsports introduces the ultimate 427ci LS Chevy-compatible long block, purpose-built for maximum boosted horsepower. Whether you’re chasing wins on the drag strip, sliding through drift circuits, tackling off-road trails, or carving up autocross courses, this engine delivers the perfect blend of power and reliability. At its foundation is a high-strength LSX-style cast-iron block, designed to handle extreme boost from nitrous, superchargers, or turbos. Topping it off are BluePrint Engines LS3 aluminum heads, paired with a BluePrint hydraulic roller cam for optimized airflow and performance across the powerband. Inside, a forged 8cwt crankshaft and forged H-beam rods provide rock-solid strength, while Mahle 2618 custom forged pistons ensure unmatched durability under pressure.
