Description

The Keith Black KB193-030 is a set of 8 hypereutectic pistons designed for SB Chevy 350 engines. These pistons feature a dish type with a 12cc volume and a bore size of 4.030 inches.

Constructed from a low-expansion 390 alloy with 16 percent silicon, they allow for tighter piston-to-wall running clearance. The pistons include fully machined head and valve reliefs, triple spiral lock rings, and CNC machined pin bores for accuracy.
