• Extended cylinder barrels for improved piston support.

• Deck Height : 9.2" 

• Siamesed cylinders: Standard 4.125” cylinder can be safely bored to 4.165” diameter. Ductile Iron sleeves and extra thick walls prevent cracking and produce excellent ring seal.

• Upgraded oiling system has been completely redesigned with a low restriction priority main oiling system with rear external oil pump feed.

• Dual crossovers allow oil flow to be metered with restrictors for roller lifter cams and/or roller rocker arms to reduce oil flow and windage.

• Reinforced head bolt bosses are blind tapped to prevent leaks and produce accurate torque readings. Extra thick decks prevent head gasket leaks.
