LS Next SHP Iron Block Parts Kit

The LS Next SHP Iron Block Parts Kit from DART is designed for serious LS engine builders and performance enthusiasts aiming to enhance displacement and horsepower in modern small-block applications. This precision-machined component kit represents the next generation of DART's renowned iron block technology, tailored for high-performance street and racing builds where reliability meets raw power.

DART's LS Next SHP iron block assembly employs proprietary casting and machining processes to achieve superior structural rigidity and thermal stability compared to stock GM units. The iron construction ensures excellent heat dissipation, which is crucial for high-boost forced-induction applications and prolonged wide-open-throttle operation. The SHP designation signifies DART's advanced manufacturing tolerances and premium-grade material specifications.

This kit is perfect for engine builders integrating LS powerplants into custom vehicles, restomod projects, or standalone racing applications. Each component is precision-finished to exacting standards, ensuring optimal honing, deck surface flatness, and bore concentricity. This attention to detail translates directly to longer ring life, reduced blowby, and improved combustion sealing, regardless of boost level or fuel octane.
