SBF Dished Piston Set 4.030 Bore -9.5cc

The SBF Dished Piston Set 4.030 Bore -9.5cc is designed for small-block Ford engine builders focused on high-compression and high-RPM performance. These forged pistons are ideal for applications where optimizing the compression ratio and ensuring valve clearance are crucial, especially in stroker assemblies and turbocharged platforms.

The pistons feature a dished crown design that effectively contributes to a -9.5cc volume per piston, enhancing the static compression ratio when compared to flat-top alternatives. With a bore size of 4.030 inches, these pistons are suitable for overbore applications in small-block Ford blocks, allowing builders to recover lost displacement while maintaining proper ring gap and piston-to-wall clearance.

These forged pistons are perfect for a range of SBF block applications, from 289 to 408 cubic inch displacement builds. They provide a reliable foundation for horsepower without compromising durability, making them an excellent choice for street strokers, bracket racers, and vintage hot rods.
