Return PolicyKeith 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 400 c.i. (4.125" bore x 3.75" stroke).

Good pistons for the money, shame they are not forged but the machining is very nice. Hate spiral locks though. Should change them to c clips
