SBC Flat Top Piston Set 4.155 Bore -6cc 181960

If you're building a high-compression Small Block Chevy engine, compression ratio directly impacts power output and combustion efficiency—and these forged flat-top pistons deliver the precision geometry you need. The -6cc dish reduces chamber volume, allowing you to achieve the higher compression ratios that serious street and racing builds demand. With a complete set of eight forged units, you get consistency across all cylinders and the durability required for sustained high RPM operation.

These pistons are engineered for reliable performance in forced-induction and naturally aspirated applications, offering the material integrity and manufacturing precision that separates quality components from budget alternatives.
