The Arrington Forged 392 crate engine does not change the displacement of the stock 6.4L HEMI engine, 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 moving parts with forged or matched high-performance parts, ready to rev higher, work harder, and increase overall power. When paired with a controller, this engine is ready to drop in as the power plant for an updated classic car or hot rod. Or use as replacement or upgrade to your modern car or truck using the OEM control systems and our custom tune.

Other displacements are available based on the 6.4L block, including the Arrington 426, or expanding up to 448 cubic inches.

Note: NO CORES required -- call if you are upgrading and want credit for trading in your existing engine.
