KB Chevy 350 Hypereutectic Pistons, .388 Dome, 5.7 Rod

							                        

                                                        
Keith Black Hyperutectic 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 350 c.i. (4.000" bore x 3.48" stroke).
