SBC Dome Piston Set 4.155 Bore +3.8cc

The SBC Dome Piston Set 4.155 Bore +3.8cc is designed for small-block Chevrolet builders who aim for enhanced compression and chamber control in high-performance applications. This piston set is ideal for both forced-induction and naturally aspirated builds, providing versatility for various engine configurations.

The +3.8cc dome geometry increases the static compression ratio compared to flat-top designs, allowing for better tuning of air-fuel ratios. With a bore diameter of 4.155 inches, this piston set is compatible with modern SBC block preparations and popular stroker crank combinations, ensuring optimal piston-to-wall clearance and ring seal integrity.

Builders of 383, 406, or 427 stroker engines will find this piston set particularly beneficial when paired with modern cylinder heads and either carbureted or EFI management systems. Its design also enhances quench characteristics, reducing the risk of detonation and allowing for higher ignition advance.
