Diamond 30806 - 5.8L Shelby Series Piston / Ring Kit -30.5cc Dish, 3.670" Bore
Diamond's all new 5.8L Trinity Shelby Series Pistons feature a much taller compression height to bring the Piston closer to the deck. This drastically improves combustion efficiency and flame travel while allowing the rings to be spaced out for additional strength. These Pistons are designed to be used in a 5.8L Block that has been sleeved.
