The Dart LS SHP Iron Block delivers the structural integrity and precision bore sizing needed for forced induction, nitrous, or naturally aspirated builds pushing past stock limits.

Whether you’re assembling a street strip weapon or a dedicated race engine, Dart’s SHP line combines proven iron construction with modern CNC machining tolerances. The 4-bolt main design provides the rigidity required for consistent performance across multiple heat cycles and high-RPM operation.
