Keith Black 390 hypereutectic dish piston set is .020 over size with a 9.0:1 compression. Piston have 3-1/2" and is alloy cast in a permanent steel mold which makes it possible to build a light weight piston that makes more power, runs quietly, uses less fuel and lasts longer than any other type of piston. The low heat transfer of the alloy keeps the skirts cool so piston expansion is minimal. Piston set includes Hasting Moly ring set. Use with a 3.812" stroke and a dish head.
**NOTE: Run engine at moderate speeds for at least 500 miles, avoiding excessive running in lower gears, in order to properly break-in new pistons and rings.
