Engine Block: Description

A high-pressure die-cast aluminum alloy block uses cast-in-place cylinder bore liners made of a proprietary "Silitec" material for wear resistance. These aluminum-silicon alloy liners reduce block weight relative to cast iron liners while providing the necessary wear resistance. Block construction features side walls extended below the centerline of the crankshaft, cross-bolted main bearing caps, and a structural cast aluminum oil pan for additional rigidity.
