SBF SHP Iron Block 4.000 Bore 9.500 DH

The SBF SHP Iron Block 4.000 Bore 9.500 DH from DART is engineered for serious Small Block Ford builders who demand a robust foundation for high-performance engine assembly. This iron block serves as the core component for stroker builds, forced induction applications, and naturally aspirated performance engines where strength and reliability are non-negotiable. Whether you're constructing a street performance engine, competition platform, or restoration project demanding modern durability, this casting provides the structural integrity required to handle elevated boost pressure, extended RPM ranges, and sustained power delivery without compromise.

Built from premium ductile iron, the SBF SHP block features a 4.000-inch bore diameter and 9.500-inch deck height, making it compatible with modern stroker crankshaft combinations and larger displacement configurations. The deep-sump (DH) design accommodates wet-sump oiling systems and allows for deeper piston travel, critical for extended stroke applications. DART's casting process ensures consistent material density, superior core shift control, and enhanced fatigue resistance throughout the block structure.

At approximately 238 lbs, this component provides the mass necessary for vibration dampening while remaining practical for engine swap installations and custom chassis applications. This block is ideal for engine builders, performance shops, and experienced enthusiasts tackling complete engine rebuilds or fresh assembly projects. With its robust design and high-performance capabilities, it is a reliable choice for anyone looking to enhance their Small Block Ford engine.
