BBM Dished Piston Set - 4.350 Bore -23.7cc

The ICON PISTONS BBM Dished Piston Set with 4.350 bore and -23.7cc displacement is a premium forged piston solution engineered for high-performance Mopar B-series engine builds. This complete set of eight pistons delivers the compression characteristics and structural integrity demanded by serious engine builders and performance shops seeking reliable power without compromise.

The -23.7cc dish configuration is critical for managing compression ratios in forced-induction and high-boost applications where controlling peak cylinder pressure prevents detonation and extends engine life. The 4.350-inch bore specification requires precise block machining and is typically chosen when maximizing displacement within B-series constraints. Standard ring groove dimensions (1/16 x 1/16 x 3/16 inches) ensure compatibility with conventional piston ring sets and maintain proper ring sealing and gas pressure management. Forged construction provides the strength required for elevated RPM operation and aggressive ignition timing curves common in street and race environments.

This piston set is specified for builders and engine shops targeting custom B-block builds where OEM components no longer meet power or durability requirements. Typical applications include street performance upgrades, bracket racing, and engine restoration projects where bore size and compression tuning are central to the build strategy. The complete eight-piston set simplifies ordering and ensures matching material properties across all cylinders—critical for consistent power delivery and minimal vibration.

ICON PISTONS maintains a reputation for precision forging and dimensional consistency within the engine building community. Builders selecting this piston set should verify compatibility with their specific block preparation, rod length, and stroke to confirm proper pin height and deck clearance before final assembly.
