Details

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
