Keith Black Pistons
Are Keith Black pistons any good? here are the specs.
Keith Black Hypereutectic pistons are a T-6 heat treat piston with the machining features of there new generation forging and utilize the properties of 390 alloy. There are significant advantages with hyper pistons in compression restricted classes. The low conductivity of the alloy and reflective piston top surface lowers oil temperature reduces combustion heat and pressure loss. Tight suggested clearances keep things quiet and reduce oil consumption.
Piston Specifications Bore Stroke Rod Length Comp/Ht Ring Size Pin Size
3.910 3.310 6.123 1.810 5/64 5/64 3/16 .984
Piston Weight Pin Weight CR/57cc CR/60cc CR/64cc CR/68cc
507g 132g 10.3 9.9 9.5 9.1
