What is Ductile Iron?
Ductile iron is a cast ferrous alloy. It always contains carbon in excess of 1.5 percent and, customarily, in excess of 3.0 percent. It also contains silicon usually from 1.0 to 4.0 percent and manganese up to 1.0 percent. In order to obtain the needed properties both phosphorus and sulfur contents must be low. Phosphorus content is usually less than 0.1 percent, preferably less than 0.05 percent. Sulfur content must be less than 0.02 percent. One more element, magnesium, is always present in ductile irons. I ts concentration normally ranges from 0.02 to 0.08 percent

Converts the factory OEM block to a wet sleeve closed deck design

Typically used on forced induction engines running 12 PSI + or NA motors that require bores > 87.5mm.

Features: -

- 130,000 PSI Tensile strength ductile iron
