zz4 forged pistons
Does anyone know were I can find stock bore forged pistons for a zz4 short block. The engine has never been ran unless they break them in at the factory. The engine is a brand new block with no over bore. example 30 over. I don't think that the rods are forged they are powered metal. Whatever that means.
