Description

The Keith Black KB203.030 is a set of 8 hypereutectic pistons designed for Big Block Chevy engines. These pistons feature a dome with a 12cc volume and a 4.280-inch bore. They are constructed from a low-expansion 390 alloy with 16 percent silicon, allowing for tighter piston-to-wall running clearance.
