Keith Black KB112.030 Flat Top 6.0 Rod SBC 350 Hypereutectic Pistons

Keith Black Hypereutectic pistons are favored for their improved power and reduced scuffing.

These T-5 heat treated pistons also offer reduced thermal expansion, which allows you to run tighter clearances and allows the piston rings to seal better and minimize blow-by. For S/B Chevy 350 c.i.
