BBC Dome Piston Set 4.310 Bore +47.4cc

The Race Tec Pistons BBC Dome Piston Set 4.310 Bore +47.4cc is a forged piston assembly designed specifically for big block Chevy applications that require elevated compression and optimized dome volume. This set of eight pistons is ideal for builders targeting high-output naturally aspirated or boosted BBC engines, ensuring performance and reliability.

Crafted from high-quality forged materials, this piston set provides the structural integrity needed for sustained high-RPM operation. The +47.4cc dome volume significantly raises static compression compared to flat-top alternatives, enhancing volumetric efficiency and torque production. The ring groove architecture adheres to the 1.5 x 1.5 x 3.0mm specification, making it compatible with standard compression and oil control rings used in modern BBC builds.

Engine builders and performance enthusiasts will benefit from the precise design of these pistons, which ensures consistent piston-to-head clearance and quench pad geometry across all eight units. This uniformity is critical for achieving optimal combustion and reducing carbon buildup, making this piston set a reliable choice for various engine configurations.
