* Dart B20+ block has extra-tall 8.900 (226mm) deck height and 84.5mm bore for increased displacement.
* Aerospace quality C355-T6 virgin aluminum alloy provides maximum strength and durability.
* Replaceable ductile iron dry sleeves are fully supported to reduce bore distortion and enhance ring seal.
* Closed deck design increases rigidity and improves head gasket sealing.
* Steel main caps with high-strength bolts increase bottom end strength and minimize bearing bore distortion.
* Strengthened main webbing increases rigidity and improves head gasket and sleeve life.
* Extra large water jackets enhance coolant circulation around cylinder barrels.
* Machined for piston oil sprayers (not included) to reduce piston temperatures and prevent detonation.
* Uses stock components, including oil pan, oil pump, water pump, alternator, and timing belt tensioner.
