Info

These are Garage Sale priced because they are an open box item, the original package was damaged in shipping.  There is some light scuffing and scratching on the pistons from shipping.

Keith Black Hypereutectic pistons are favored for their improved power and reduced scuffing. The unique design & manufacturing processes combine to produce a rigid piston, which will rock less in the bore improving ring seal. 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 383 c.i. (4.000" bore x 3.75" stroke).

  • 390 Hypereutectic alloy
  • 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
  • Lightweight wrist pins
