Mopar just made it easier to shove a new Hemi into your old hot rod

Its new Crate Hemi Engine Kits make the engine swap nearly plug-and-play.


See that small amount of wiring? That's all it takes to get this crate Hemi up and running.


Engine swaps can be frustrating and complicated, especially with new engines and all the complicated wiring that goes with it. In order to make the process easier, Mopar just released a kit that makes the whole process as easy as possible.

The Mopar Crate Hemi Engine Kit works with 5.7-liter and 6.4-liter Hemi V8 engines from 2014 on. The kit is meant to pair the new engine with a pre-1975 vehicle. It includes a power distribution center, powertrain control module, engine and chassis wiring harnesses, a number of sensors and even a gas pedal. Yes, there's also an instruction manual.

The engine kits also include factory software calibration. The 5.7-liter Hemi will put out 383 horsepower and 425 pound-feet of torque, while the 6.4-liter should spit out 485 horsepower and 472 torques. That's plenty of twist, and the kits are already in use on two SEMA concepts -- the Jeep CJ66 and Dodge Shakedown Challenger.

Mopar claims this turns an engine swap into a nearly plug-and-play situation. There are, of course, exceptions. For example, these kits are best paired with manual transmissions. Automatics will work, but are "not optimal." You can also add on options like power steering and air conditioning.

Making things easier never comes cheap. The Mopar Crate Hemi Engine Kit costs $1,795, no matter which V8 you're buying it for. You can purchase the kit by itself, or you can head to Mopar's website and grab both the kit and a brand-new crate motor at the same time.

Wires? I've got your wires right here, bucko.
