SBC Dished Piston Set 4.030 Bore -24cc

The SBC Dished Piston Set 4.030 Bore -24cc from Sportsman Racing Products is designed for serious small-block Chevrolet builders who require precise compression control without sacrificing reliability. Dished pistons are particularly beneficial for forced-induction builds, alcohol racing, or high-boost applications where detonation resistance is essential.

This piston set features a -24cc dish depth, indicating that the crown is recessed 24 cubic centimeters below the deck surface, which is crucial for accurately calculating static compression ratios in various engine combinations. The 4.030-inch bore size is suitable for overbored blocks, allowing builders to maximize displacement while using existing crank and rod packages. Sportsman Racing Products manufactures these pistons to strict tolerances, ensuring consistent ring gap clearance, pin bore alignment, and wall thickness across the set.

Engine builders, competitors, and street machine enthusiasts will find this piston set particularly advantageous when assembling small-block Chevrolet stroker or overbored packages intended for turbocharged or supercharged applications. The design promotes smoother operation, reduced blowby, and extended engine life under high RPM and boost conditions.
