Hemi Engines for Sale

HEMI engines have for years set the standard for raw power and performance that’s uniquely American, and they’re most closely tied to brands under the Stellantis umbrella. For many a car nut, the name HEMI is inextricably linked with Dodge, and it’s easy to see why. Whether you’re talking about the aggressive snarl of a Charger or the in-your-face attitude of a Challenger, Dodge has employed the HEMI V8 to stake its claim as a maker of serious American muscle cars, and that engine does a lot more than just churn out numbers: it embodies attitude, heritage and a driving experience that’s as raw as it is downright exhilarating.

Of course, HEMI engines aren’t just found on muscle cars; they also get a serious workout with Ram Trucks. Whether you’re talking about a 1500 or a heavy-duty workhorse, the HEMI delivers the kind of torque and durability that truck buyers rely on day in, day out for towing, hauling and the daily grind. Meanwhile, Jeep has used HEMI power to turn utilitarian SUVs on their head - especially in high-performance trims of the Grand Cherokee that somehow manage to balance practicality with high speed.

Even Chrysler has gotten in on the action, embracing the HEMI legacy in the 300, while Plymouth played a huge part in putting the HEMI on the map during the heyday of American muscle. And when you put all of these brands together, what you get is an engine that’s become an icon - rather than just a piece of engineering.

What Are Hemi Engines?

Hemispherical combustion chambers, A.K.A. Hemi engines, are high-power, input combustion-efficient engines popularised by Chrysler in various models like Dodge Charger, Dodge Challenger, Ram 1500 and Jeep Grand Cherokee.

HEMI Crate Engine vs Used HEMI Engine

The HEMI crate engines are brand new engines with zero miles run and backed by a manufacturer’s warranty. These engines are far more costly than a used HEMI engine, but will offer a better fresh start to your car, giving the utmost performance. The used or remanufactured Hemi engines, on the other hand, are affordable and, if bought from a reliable partner, can offer you a verified mileage and service record.

Benefits of HEMI Engines

There are several benefits of opting for a HEMI engine over a normal engine. As the name suggests, the hemispherical combustion chamber offers a better flow of air, horsepower, and combustion. Compared to normal engines, these have faster acceleration and thus speed, and strong torque for towing. These engines are compatible with muscle cars and trucks like the Ram 1500 and the Dodge Challenger, giving them better performance and reliability. Additionally, there is wide availability for parts of these engines, and it is also easy to upgrade the HEMI engines to the latest version. These engines actually last way longer than any average engine when maintained properly. Finally, they come in different sizes, including the 5.7L, 6.4L, and 6.2L, thus fitting various budgets.

Disadvantages of Hemi Engines

The higher performance of engines of HEMI comes with a price; they consume more fuel when compared to the average V6 or V8 engines and are far more expensive than the other engines. If you want a fuel-efficient engine, then this engine is not your cup of tea. They demand premium, higher-performance fuel. The maintenance cost is also much higher than the actual expectation, and these engines are heavier than the base options; this might affect the balance of the whole vehicle. The replacement of these engines could also be expensive. So think wisely, sort out your priorities before opting for these engines.

Main Types of HEMI Engines

The First-Generation HEMI engines, which were introduced in the 1950s, also known as the “FirePower”, were hemispherical V8 engines introduced by Chrysler. Late,r the 426 HEMI was introduced in the 1960s-1970s. These engines were known as the “Elephant Engine” and were well popular for their performance and were employed in classic muscle cars like the Dodge Charger.

Then comes the Third-Generation 5.7L HEMI, which was produced from 2003 to the present. These modern HEMI engines are used in vehicles like the Ram 1500 and Dodge Charger.

Other important types of HEMI engines are 6.1L HEMI, 6.4L (392) HEMI (which were used in Dodge Challenger SRT 392), 6.2L Supercharged HEMI (A.K.A. Hellcat or Redeye) and 426 HEMI Crate Engine popularly used in Modern Reissue.

Fitment

Considering the fitment, there are basically three types of HEMI engines. The 5.7L HEMI is apt for the Dodge Charger, Dodge Challenger, Ram 1500, Jeep Grand Cherokee, and Chrysler 300. The 6.4L (392) HEMI is used in Dodge Challenger SRT 392, Dodge Charger SRT 392, Jeep Grand Cherokee SRT, and Ram 2500. And the 6.2L Supercharged HEMI is employed in Dodge Challenger SRT Hellcat, Dodge Charger SRT Hellcat, Ram 1500 TRX, and Jeep Grand Cherokee Trackhawk.

The HEMI engines could also be used in other models other than this, such as the engines of Charger, Challenger and Chrysler 300, which could be swapped, as well as the engines of Ram 1500 and Ram 2500 can be swapped with a transmission compatibility check. This cross model fitment can only be possible if the engine generation, ECU and wiring harnesses match.

The HEMI engines could be used in other makes, too. This might need minor mounts and fabrications. Some of such cross-fits are the Classic Ford Mustang, Chevrolet Camaro custom builds, Chevrolet C10 trucks, Toyota Supra, and older Jeep Wrangler models.
