Mopar 392 Crate 6.4-litre HEMI Engine Kit

If you’re one of those HEMI enthusiasts who has long thought about easily fitting one of the modern HEMIs in your ’Cuda, Fiat Chrysler has good news for you with the introduction of crate engine kits that allow the pairing of modern 5.7-litre or 6.4-litre HEMI engines with model year 1975 or earlier vehicles

Selling for $1,795 US, the kits consist of a power distribution center, powertrain control module (PCM), engine and chassis wiring harnesses, accelerator pedal, O2 sensors, ground jumper, charge air temperature sensor and in-depth information sheets, to make a virtual plug-and-play endeavour out of dropping one of the Gen III HEMI engines (sold separately) into a Dodge Charger or Challenger, Plymouth ’Cuda and many other makes and models.

The Mopar 345 Crate HEMI Engine Kit is meant for the 5.7-litre V-8, the Mopar 392 Crate HEMI Engine Kit is meant for the 6.4-litre V-8. They’re compatible with 2014 or newer engines, and available through Fiat Chrysler Automobile (FCA) dealers or online at the new Mopar site.

“Our new Mopar Crate HEMI Engine Kits answer enthusiast demand for a relatively simple solution for plugging modern-day HEMI engine power into their classic Mopar rides,” said Pietro Gorlier, Head of Parts and Service (Mopar), FCA – Global at the announcement of the kits during the recent Specialty Equipment Market Association (SEMA) Show in Las Vegas. “The engine kits include the hardware to plant a 5.7-litre or 6.4-litre HEMI engine under the hood with the factory-backed confidence that comes when using Mopar parts. They also offer optional front-end accessory kits like power steering or even exhaust manifolds to make installation easier. Starting today, our fans can order the kit online and start working on their favorite project with the peace of mind that comes when using a Mopar product.”

The unlocked PCM features a factory calibration, that takes horsepower of the 5.7 V-8 to 383 hp and torque to 425 lb-ft, and the 6.4-litre engine to 485 and 472, respectively. They’re meant for be used with manual transmissions though they can be adapted to use with the Torqueflite automatics.

Other components available include a power steering expansion kit, AC expansion kit and rear sump oil pan kit. And it’s all covered by a Mopar 2-year/unlimited mileage warranty.
