Tool Stroker Combinations

Keith Black hypereutectic pistons are made from 390 alloy and heat-treated to T6 standards, which makes them 30 percent stronger than ordinary untreated hypereutectics. Their 100 percent CNC-machined crowns, high upper compression-ring location, gas-accumulator groove, drilled oil returns, and spiral-lock retainer grooves make these pistons outstanding for performance applications. On top of that, Keith Black's hypereutectic pistons have a lightweight, rigid-rib skirt design that stabilizes the piston in the bore. All of this adds up to pistons that fit tighter than forged types, provide improved oil control, reduce blowby, increase ring life, eliminate cold start-up knocking, and won't cost you an arm and a leg!

Due to the multiple variables possible with any engine combination, all compression ratios listed are approximate. To accurately calculate the static compression ratio of any engine, the following values must be known: Bore diameter, stroke length, rod length, deck height, combustion chamber volume, cylinder head gasket compressed thickness, and cylinder head gasket bore diameter.
