6.4 HEMI Based Long Block (392 and up)

The Chrysler V8 6.4L HEMI engine has been available since 2011 under the SRT and Scat Pack configurations and is the highest power option available for most of the Dodge, RAM and Jeep cars and trucks. Always looking to do better, Arrington uses this block, replacing all of the moving parts with forged, high-performance upgrades for a more powerful result, suitable for high-boost applications (turbocharged or supercharged) or higher-power, higher-displacement naturally aspirated setups.

The Arrington Forged 392 long block does not change the displacement of the stock 6.4L HEMI block, but upgrades the components for higher-performance applications, including forced induction. The Chrysler 6.4L HEMI is notorious for failing when pushed by a supercharger or turbocharger at 8 psi boost or more. We replace all of the non-forged moving parts with forged or matched high-performance parts, ready to rev higher, work harder, and increase overall power. Think of it as an upgrade for...
