SBC Dished Piston Set 4.030 Bore -16cc

The SBC Dished Piston Set 4.030 Bore -16cc from Sportsman Racing Products is a forged small-block Chevy piston set designed for high-performance marine and racing engines where precise compression ratios and reliable power delivery are essential. This product is tailored for serious boaters and engine builders who demand consistency across all eight cylinders.

Each piston in this eight-piece forged set features a 4.030-inch bore diameter with inverted dome geometry and -16cc displacement reduction, which lowers compression volume. This design is ideal for naturally aspirated engines requiring conservative compression ratios or those running on regular-grade fuel. The ring groove configuration of 1/16 x 1/16 x 3/16 inches accommodates standard compression and oil-control rings, ensuring proper sealing and blow-by management.

This piston set is particularly beneficial for small-block Chevy engine rebuilds in displacement ranges from 283 to 400 cubic inches. The forged construction provides superior strength and heat resistance compared to cast alternatives, making it critical for sustained high-rpm operation in marine powerplants. Whether rebuilding a performance cruiser or optimizing a racing platform, this piston set enhances fuel efficiency, detonation resistance, and overall engine longevity.
