From big and powerful workhorses to sleek and fast performance coupes, Dodge has solidified its reputation among American car brands thanks to its lineup of engines.
Thus, many are also looking for the possibility of swapping such Dodge engines from one model to another, but don’t know where to start.
But not to worry, as that’s exactly where this guide comes in! We’ll be going over several different Dodge engines and all of the models that they’re compatible with!
Which Dodge engines are compatible with Dodge vehicle models?
4.7L, 5.2L, and 5.9L V8s are compatible with the Dodge Dakota, Durango, and Ram.
6.7L I6s are compatible with Ram 2500s and 3500s, while the 6.4L V8 also includes the Ram 4500 and 5500.
HEMI engines (5.7L, 6.1L, 6.2L, 6.4L, 7.0L V8s) are compatible with Chargers, Challengers, RAM HD models, and more.
To give you a more comprehensive guide, we’ve made a compatibility chart that lists all of the Dodge engines as well as their respective specs and vehicle models that they can be paired with below.
As an added bonus, we’ve provided a bit of background on each of these engines further down, so you know what to expect before committing to swapping them into your Dodge vehicle.

2.2L/2.5L Inline-4 (I4)
The 2.2 and 2.5-liter engines are the only Dodge 4-cylinder engines on this list, and they’ve been mostly known for powering many Dodge L-platform cars of the 80s and 90s, such as the 6th-gen “L-body” Dodge Charger.
Apart from being the smallest engines on this list, the Dodge Inline-4 (I4) engines also produced the least horsepower when starting from the naturally-aspirated 2.2-liter carbureted version at 84 hp.
Later turbocharged versions of the 2.2-liter allowed its horsepower figures to peak at 224 hp. However, the 2.5-liter version actually made less horsepower (168 hp) even in its turbocharged form.
The 2.2-liter I4 can be found in Dodge models such as the 024, 400, 600 Aries, Caravan, Daytona, Omni, Lancer, Rampage, and Shadow.
The bigger 2.5-liter option, however, was specifically used in the Dodge 600, Aries, Caravan, Daytona, Dynasty, Lancer, Shadow, and Spirit.
6.7L Cummins Inline-6 (I6) Turbo Diesel
Moving on to an engine with two more cylinders, the 6.7-liter inline-6 Cummins engine is, yet again, the only “straight-six” engine on this list.
Part of the “B-series” family of engines, the turbocharged 6.7-liter Cummins is also the only diesel engine on this list as well as the only engine to be created by an independent company.
Because of its very high torque figures (about 610 to 1,000 lb-ft of it), it has found its home underneath the hood of the Ram 2500 and Ram 3500 heavy-duty pickup trucks from 2007 until the present day.
Pair the 6.7-liter Cummins I6 up with a compatible transmission such as Aisin 6-speed auto or the 68FE 6-speed manual/auto, and you’ve got yourself a formula that has some serious hauling and towing power if you put them in a Ram truck.
Just take note that earlier model years of the engine may have lesser power compared to newer ones. Thus, the newer you go, the better off you’ll be in terms of performance and updates.
3.7L Powertech V6 (EKG)
The 3.7-liter Powertech V6 is the smallest of the Powertech series of engines, and it has been used in many of the Chrysler brand’s (now Stellantis North America) vehicles.
But since this is a Dodge guide, after all, the most important models to mention that are all powered by the 3.7-liter V6 include the Ram 1500, Dakota, Durango, Nitro, and even the M80 Concept from 2002.
Also called the “EKG” V6, the 3.7-liter V6 has been used in the abovementioned models from 2002 to 2012 before eventually getting replaced by the newer Pentastar V6 engine.
Throughout its 10-year run, the 3.7-liter V6 EKG has maintained its power output at 210 hp, regardless of vehicle model.
However, swapping the engine from one compatible model to another may require you to change the components of the crankshaft, especially those made between 2004 and 2005.
3.9L V6 (Chrysler 239)
The 3.9-liter V6, also called the “Chrysler 239”, is an older V6 engine made by the Chrysler Corporation for use in various Dodge vehicles from 1987 to 2003.
Being used mainly as a base motor, the 3.9-liter V6 has been mostly known to power the 1st and 2nd-generation Dodge Dakota pickup truck.
In addition, other models such as the Ram 1500, Ram Van, and their Magnum versions also utilize all 175 to 180 horses produced by the 3.9-liter V6.
It’s also worth noting that the 3.9-liter V6 is closely related to Chrysler’s older “LA 318” V8, as the former literally has the same bore and stroke (99.3x84mm) except having 2 fewer cylinders than the latter.
The engine received multiple updates to its fuel injection over the years. It initially used a two-barrel Holley carburetor in 1987 before switching to a throttle-body fuel injection setup the following year.
1992 versions of the 3.9-liter V6, however, already switched to a multi-port fuel injection system, while the final 1997 update equipped it with a sequential fuel injection system that stuck until the engine was discontinued in 2004.
4.7L Powertech V8
As the first of several V8 engines stamped with the “Powertech” badge, the 4.7-liter Powertech V8 provides ample power to certain Dodge vehicles of the early to mid-2000s.
The 4.7-liter V8 primarily powered three different Dodge models from 1999 to 2009, namely the Dodge Dakota, Dodge Durango, and Dodge Ram 1500 of those years.
Pairable with either a 4-speed automatic or a 5-speed manual transmission, the 4.7-liter V8 puts out 235 hp on all of the abovementioned applications.
4.7L V8 (High-Output/HO)
If you crave slightly more power out of the same base engine, you can opt for the “High-Output” version of the 4.7-liter Powertech V8 engine.
Compared to the standard engine, the High-Output version puts out between 265 to 310 hp to the crank depending on the exact vehicle application.
The 4.7-liter HO V8 is also compatible with the Dodge Dakota and Dodge Ram 1500, though sadly, it was never used to power the Dodge Durango SUV.
Hence, you can only interchange engine parts between the Dakota and the Ram 1500, specifically, models made between 2002 and 2008.
Furthermore, keep in mind that the camshaft, intake manifold, fuel injectors, valves, cylinder heads, connecting rods, and ECU are not identical between the standard version and the high-output version.
5.2L Magnum V8
A bigger-displacement V8 engine for certain Dodge Dakota, Durango, Ram, Ramcharger, and Ram Van models exists in the form of the 5.2-liter Magnum V8.
Suitable for the 1992 to 2002 model years of the vehicles mentioned above, the 5.2-liter V8 produces 230 hp in all applications.
Despite being bigger than its Powertech successors, the 5.2-liter V8 is actually a “small block V8” and is the smallest of the Magnum V8 engines in terms of displacement.
It’s also worth mentioning that the design features and upgrades for the 5.2-liter V8 are also identical to its bigger brother, the 5.9-liter Magnum V8, so part interchangeability is possible to some extent between the two.
However, some modifications like replacing the ECU, neutral flexplate, and torque converter are required when swapping between models that either have a 5.2-liter or 5.9-liter Magnum V8.
5.7L HEMI V8
The HEMI series of engines, which is called such because of its hemispherical cylinder head design, is the successor to the LA/Magnum series and starts off with the 5.7-liter HEMI V8.
The 5.7-liter HEMI V8 is used as the base engine in several different well-known Dodge models from 2003 to the present day, such as the Challenger, Charger, Magnum, and Ram.
Depending on the exact vehicle application and model year, the max power output for the 5.7-liter V8 peaks out at 340 to 399 hp, which actually makes it the least powerful out of all the modern HEMI engines.
There are some differences between certain model years that may make swapping not possible. For instance, 2009 models have received updates to their cylinder heads, which made them longer compared to those fitted in 2003 to 2008 models.
Furthermore, 2009 models also have different front covers and composite intake manifolds compared to models made before that year.
5.9L Magnum V8 (Chrysler 360)
As the bigger version of the 5.2-liter V8 engine we’ve discussed earlier, the 5.9-liter Magnum V8 is used in the same Dodge models as the former is fitted in, which includes the Dakota, Durango, Ram, Ramcharger, and Ram Van.
But in addition to such models, the 5.9-liter V8 is also used to power the Dodge Ram Wagon from 1992 to 2003.
The 5.9-liter V8 initially started off with 230 hp when it debuted in 1993. But by the 1998 model year, power (as well as torque) was bumped up to 245 hp in the heavy-duty version of the engine.
As with its smaller 5.2-liter sibling, the 5.9-liter V8 also requires you to take the ECU, flexplate, and torque converter from the original engine that you’re going to be swapping out.
6.1L HEMI V8
The 6.1-liter HEMI V8 is considered the middleweight among the HEMI engines, and you can find it in the same vehicles that the base 5.7-liter HEMI V8 powers as well, except for the Ram pickup truck.
A step above the 5.7-liter version, the 6.1-liter HEMI V8 is rated at 425 hp for the SRT-8 trim of the Dodge Challenger, Dodge Charger, and Dodge Magnum models between 2006 and 2010.
Compared to the 5.7, the 6.1-liter V8 has upgraded internals such as lightweight pistons, more durable connecting rods, and a forged crankshaft.
6.2L Supercharged HEMI V8 (Hellcat/Demon)
If you ever wanted to opt for the most powerful and extreme version of the HEMI engine, then look no further than the 6.2-liter HEMI V8.
Coupled with a 2.4-liter twin-screw supercharger, the 6.2-liter HEMI V8 provides unparalleled levels of performance exclusively for Dodge’s SRT Hellcat, Demon, and RAM TRX models (apart from the Jeep brand’s “Trackhawk” SUV).
When it debuted in 2015 for the Challenger Hellcat and Charger Hellcat models, the supercharged 6.2-liter V8 already made a whopping 707 hp out of the box.
Performance levels only continued upward from there with the introduction of the Challenger Hellcat “Redeye” model in 2019, which was equipped with a 797-hp version of the engine.
But it still didn’t stop there, as a limited-edition drag-strip-ready “SRT Demon” model had the 6.2-liter V8’s power levels bumped up to 808 hp on pump gas and up to 840 hp on 100-octane race gas.
If off-roading is more of your thing, then you’ll also find the Hellcat version of the engine fitted in the 3.2-ton Ram 1500 TRX truck, which gets propelled from 0 to 60 in a mere 4.5 seconds.
Keep in mind that only models equipped with the supercharged 6.2-liter V8 can swap engines with each other, as they are the only Dodge models equipped with transmissions that can handle such power levels from the top-spec HEMI engine.
In addition, there is actually a crate engine version of the Hellcat engine that’s sold by Mopar starting in 2017, which is advertised to be a “plug-and-play” kit that can even be swapped into pre-1976 classic Dodge models.
6.4L HEMI V8 (392 HEMI/Apache)
Another notable engine that’s part of the HEMI family is the 6.4-liter V8, which is one step higher than the 6.1-liter HEMI V8 in terms of performance specs.
Also known as the “392 HEMI” or “Apache”, the 6.4-liter HEMI V8 is used by Dodge to power several SRT and R/T models of the Challenger, Charger, and Durango.
While it initially made 525 hp for the pre-production crate engine version back in 2005, the production version of the 6.4-liter HEMI V8 actually made 470 hp and up to 485 hp for 2015 and newer models.
Some differences to take note of include different cylinder heads and pistons for the 2013 and newer engines, so you won’t be able to use them in those from 2011 to 2012.
But since the 6.4-liter “Apache” V8 is essentially based on the 5.7-liter V8, there is still some part interchangeability between the two engines, such as the water pumps and timing cover.
Just be sure to take the same wiring harness off of the old engine and use it on the new one, as the electronics wouldn’t work right otherwise.
7.0L HEMI V8 (Chrysler 426 HEMI)
If you’re a fan of more classic builds, then you can turn to the good old 7-liter HEMI V8 that’s found in several Dodge Challenger, Charger, Coronet, Dart Super Stock, and Super Bee models dating back all the way to 1966.
With 426 cubic inches of displacement, the original 7-liter HEMI V8 also earned the nickname “426 HEMI”, and made between 350 to 425 hp for the classic 1966 to 1971 models.
When it comes to swapping engines between models that have the 7-liter V8, you will actually not have much difficulty interchanging various parts due to most of them being exactly the same.
Just keep in mind that the original 7-liter HEMI V8 is an old engine, after all, so you will have to inevitably deal with finding a sample (including a suitable transmission) that’s well-maintained.
But the good news is that Mopar has created a modern version of the 7-liter HEMI engine dubbed the “Mopar 426 HEMI”, a 590-hp V8 that was unveiled along with the Dodge Charger “Redline” in 2012.
8.0L Magnum V10 (Chrysler 488 Magnum)
As the first 10-cylinder engine on this list, the 8-liter Magnum V10 was only used in certain heavy-duty Dodge vehicles that need this level of “oomph”.
With its large dimensions and even larger displacement, the 8-liter V10 was made to be the heart of the Dodge Ram 2500 and Ram 3500 heavy-duty trucks from 1994 to 2003.
While it only made a seemingly low 300 to 310 hp by today’s standards, the 8-liter V10’s low-end torque was more than enough to provide great towing capability for the Ram trucks of its time.
You can swap the 8-liter V10 engine with any Dodge model that originally comes with a V10 (like the Ram trucks we’ve mentioned). Just make sure to use a Dodge transmission that’s made for a V10 as well.
8.3L V10 (Viper V10/506ci)
We’ve saved the biggest-displacement engine on this list for last, as the 8.3-liter “Viper V10” engine is in a league of its own despite having already been discontinued.
The behemoth 8.3-liter V10, with its 506 cubic inches of displacement, can only be found sitting under the hood of the Dodge Viper SRT-10 and Dodge Ram SRT-10.
It initially made 510 hp when it was introduced with the 3rd-gen Viper in 2003, but updates such as the inclusion of variable valve timing and a slight increase in displacement allowed its power to peak at 645 hp for the 2015 Dodge Viper.
In order to swap such an engine into your vehicle, it better be either a Viper or Ram SRT-10 model as well, as it will require extensive (and expensive) work to make the 8.3-liter V10 fit in any other Dodge vehicle.
However, since the 8.3-liter V10 is essentially a 5.9-liter V8 with two extra cylinders by design, interchanging parts is still possible to some extent between the two due to the latter being a long block engine.
