13. 6.2-Liter Hellcat V8

The most popular, highly sought-after third-generation Hemi engine is the famous 6.2-liter Hellcat V8. This engine was born when Chrysler engineers mounted an enormous 2.4-liter supercharger on top of the already powerful stock Hemi V8.

The result was astonishing with 707 HP and 650 lb-ft. It is one of the most powerful street-legal engines currently on the market as well as one of the most powerful muscle engines ever. They first intended it for installation in the Challenger Hellcat. However, due to high demand, it is available in the Charger Hellcat and from 2018, in the Jeep Cherokee Trackhawk, too.

14. 6.2-liter Hemi Demon V8

If you think the insane Hellcat V8 with 707 HP is not powerful enough, there is the 6.2-Liter Demon V8 built by the same guys in the Chrysler SRT department. This powerplant delivers 820 HP and is available in limited production. It is also in the track-ready Dodge Challenger Demon.

The Demon is more than a Hellcat with more boost and over 100 HP more. Even though these two engines share similar architecture and blocks, there are over 25 important differences between the two.

15. 6.4-Liter 392 Apache Hemi V8

The last engine on this list started as a crate engine that the Chrysler Mopar division produced. They based the Apache Hemi V8 on the revamped 5.7-liter version. The 392 is a naturally-aspirated Hemi with performance additions. The output is 532 HP and 510 lb-ft of torque. They introduced this engine in 2007 as a crate engine, but in 2011 they installed it in the Dodge Challenger SRT.

Since they offered this unit as a replacement engine and crate item, it proved to be popular with restomod guys. In fact, the 392 was the perfect replacement engine for people who wanted to restore older muscle cars but also give them a modern drivetrain and drivability. The 392 Hemi V8 with 532 horses had almost the same HP as the original 426 Hemi. But, it was much more docile on the street and easier on fuel, too.

The powerful and dependable Hemi engine is legendary and world-renowned. Fortunately, car manufacturers will continue to use the Hemi in future production models, improving it with each generation. No one wants to see the famous Hemi engine go away, so it should be around for many years to come.
