Description

The Keith Black KB364.030 is a set of eight hypereutectic pistons designed for Ford SB 302 and 393W stroker engines. These pistons feature a 4.030 inch bore and a 22cc dish volume with two valve reliefs.

Constructed from a low expansion 390 alloy with 16 percent silicon, these pistons allow for tighter piston-to-wall running clearance. They include fully machined head and valve reliefs, triple spiral lock rings, and CNC-machined pin bores for accuracy. Additional features include an accumulator groove for enhanced compression ring seal, machined oil returns, and diamond-finished skirts.
