The Gen III Hemi has had some success as a swap, but not nearly what it should for an engine capable of 525 hp. The Hemi can compete with all the new crate engines and Chrysler finally put it on the same playing field by offering plug-n-play crate kits.

Chrysler unveiled new 392 and 345 crate engine kits under the bright lights of the Mopar booth at SEMA 2016. Crate engine kits start with basic 392, 6.4-liter; and 345, 5.7-liter, engines. The 6.4-liter engine is rated at 485 hp and 475 lb-ft. of torque, while the 5.7-liter engine has 383 hp and 425 lb-ft. These engines are in manual transmission configuration and have the least amount of tech, like the MDS system, which shuts off cylinders for improved economy. The electrical system, the largest concern with a modern engine swap, has also been simplified. The installation kit includes sensors, engine-wiring harness, accelerator pedal, power distribution center and powertrain control module (PCM). The PCM is also simplified and unlocked, allowing tuning access. Additional kits are available for front engine accessories, AC, oil systems and application-specific manifolds.
