(Part #474172)
                        

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 Chevy 377 c.i. (4.125" bore x 3.48" stroke x 5.7" rod) and Chevy 400 c.i. (4.125" bore x 3.75" stroke x 5.565").

  • Full floating wrist pins
  • Triple wound spiral locks
  • Reflective alloy allows 2% power increase
