These pistons feature internal lightening, lightweight pins and a modern (1.5/1.5/3MM) ring pack. They are available in both dished and flat top versions, 4.350 bore to start. We can alter the basic design of this piston for different bore sizes, or compression distance and pin diameter (for your fire breathing 470 combo, for example!) for a nominal charge.
