Info

Keith Black Hypereutectic pistons are T-6 heat treated and offer reduced scuffing and improved durability over stock replacement pistons. They also allow you to run tighter clearances because of reduced thermal expansion, which means more race winning power.

  • Fully machined crowns and valve reliefs
  • Drilled oil drain backs
  • Full floating wrist pins
  • Triple wound spiral locks
  • Reflective alloy allows 2% power increase
  • Quench dome technology minimizes deterioration
  • Zero deck quench designs

For Ford 347 c.i. (4.00" bore x 3.40" stroke). Use piston ring Style C (1/16", 1/16", 3/16").
