Hypereutectic Pistons
Keith Black pistons have several important advantages over conventional alloy pistons. High silicon content yields superior thermal and wear char- acteristics, greater strength, scuff and seizure protection, and resistance to cracking. High silicon content also keeps heat in the combustion chambers, eliminating heat transfer and improving combustion. Pistons are machined
with wrist pins (except Ford 2300cc, sold in sets of four).

Notes: * Signifies piston machined for 1/16" top, 1/16" second and 3/16" oil rings. Compression ratios are based on a 64cc combustion chamber.
Claimer Series Performance Pistons
Achieve maximum performance with high piston ring placement and low thermal con- ductivity. Top rings operate at higher temps and require slightly larger end gaps (4.000" gap). It is recommended that ignition timing sets of eight with wrist pins.
