SBF Dished Piston Set 4.030 Bore -14.5cc

The SBF Dished Piston Set 4.030 Bore -14.5cc from Sportsman Racing Products is a forged Small Block Ford piston set engineered for high-performance marine engine builds. This set of eight pistons features a dished dome design with a 4.030-inch bore and -14.5 cubic centimeter compression chamber, making it ideal for serious boaters and marine engine builders seeking optimized combustion efficiency and power delivery in demanding saltwater and freshwater conditions.

Built from forged material for durability under sustained high RPM operation, these pistons incorporate 1/16 x 1/16 x 3/16-inch ring grooves that promote consistent ring seal and reduce blow-by across the power band. The inverted dome profile and negative 14.5cc compression displacement are designed to work within specific engine configurations and fuel octane requirements common in marine performance applications. The 4.030-inch bore dimension ensures compatibility with properly bored Small Block Ford blocks, a foundational specification that must match your engine's exact machining before installation.

This piston set is intended for experienced marine mechanics and serious engine builders who understand the critical tolerances involved in Small Block Ford rebuilds and performance tuning. Whether preparing an inboard powerboat engine, a performance fishing vessel, or a marine rebuild project requiring matched high-quality components, this Sportsman Racing Products piston set delivers the precision and material quality expected in competition and extended-use marine environments. Proper installation requires mic-checking all components and verifying clearances with a qualified marine engine builder before assembly.
