Premium Pistons without the Premium Price
Pontiac 400 L4
Silv-O-Lite's Keith Black Signature Series pistons are packed with power-building features, yet won't cost you an arm and a leg.
 
KB Piston Features:
  • T6 heat-treated, 16-18% silicon hypereutectic alloy,
    30% stronger than untreated alloys
  • Lightweight, rigid rib skirt design to stabilize piston
  • 100% CNC-machined crowns
  • Diamond turned piston tops reflect heat into combustion chamber
  • High top ring location and high strength ring lands
  • Drilled oil returns and pin oil supply
  • .072" spiral wound pin retainers for use with floating pins (included)
All this adds up to a tighter fit for improved oil control, reduced blowby, increased ring life, and no cold startup knock!
Note: Compression ratios vary depending on cc of head
