Mopar Crate Engine Kits: 345 and 392 Hemi (w/video)

Released at 4:26 pm PST, 11/1/2016

Mopar launched several create Hemi engines on November 1, 2016, to make it easier to plug factory-backed engines into iconic Mopars. The 345 and 392 Crate Engines (5.7 and 6.4 liters) can be paired with cars and trucks up to model-year 1975 - and are available for ordering today, through dealers or the Mopar site.

Why stop at 1975 when the 1976 cars are so similar? It's all got to do with obeying the law. 1975 is legal; 1976 is not.

Pietro Gorlier, Mopar's chief, wrote, "The engine kits include the hardware to plant a 5.7-liter or 6.4-liter 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."

That allows owners to inject modern Hemi power and efficiency into muscle-car era cars and trucks such as the Dodge Charger and Challenger, Plymouth 'Cuda and Road Runner, Duster and Dart, and D-series trucks.

The engines include a power distribution center, a powertrain control module (PCM), engine and chassis wiring harnesses, accelerator pedal, oxygen sensors, ground jumper, charge air temperature sensor, and installation information.

The unlocked factory PCM has a custom calibration; the Mopar 345 Crate Hemi Engine Kit bumps horsepower to 383 and torque to 425 lb.ft. for the 5.7-liter (well above production stock), while the 392 Crate Hemi Engine Kit keeps the 6.4 at 485 horses and 472 lb.ft. of torque. The engines are designed for manual transmissions; automatic transmissions, such as the Torqueflite 727 and 904, while not optimal, can also be adapted.

Mopar has put together accessory hardware kits including power steering, air conditioning, and a rear sump oil pan.

Both the 345 and 392 engines list at $1,795, not including the engines; they can be used with a 2014 or newer Hemi engines, or purchased with new V8s. The Mopar Crate HEMI Engine Kits feature a Mopar two-year/unlimited mileage warranty.

Two Mopar-customized vehicles created for the 2016 SEMA Show feature new Mopar Crate HEMI Engine Kits underhood: the Dodge Shakedown Challenger and Jeep® CJ66 (note: both pages have been updated.)

Mark Worman, of the Graveyard Carz TV show, used a kit to build a 392 Hemi into his personal 1971 Plymouth 'Cuda, combining it with a Tremec T56 Magnum transmission. A pure, ground-up restoration, aside from the powertrain and a tweaked graphic, it uses over a hundred Mopar parts.
