The Chrysler EZB or HEMI 5.7 5.7-liter V8 engine was produced in Mexico from 2004 to 2008 and was installed on top versions of well-known models such as the 300C, Charger or Grand Cherokee. This power unit was equipped with an MDS half-cylinder off-load system.
The Chrysler HEMI 5.7 EZB engine features a cast-iron block and two aluminum heads with hemispherical combustion chambers, a single camshaft (OHV), and two valves per cylinder (16 valves in total). The Chrysler HEMI 5.7 engine used an electronically-controlled Sequential Multi-Port Electronic Fuel Injection system, distributorless, coil over plug ignition system with two spark plugs per cylinder and Multi-Displacement System (MDS), which enabled the engine to switch from eight to four-cylinder operation.

- Dodge Charger 1 (LX) in 2005 – 2008;

Disadvantages of the EZB engine
- The motors of this series are very reliable, the owners complain only about the high consumption;
- For the normal operation of the MDS system and hydraulic lifters, 5W-20 oil is required;
- With prolonged use of low-quality fuel, the EGR valve sticks here;
- Also, sometimes the exhaust manifold leads, so much so that the fastening studs burst;
- Often heard strange sounds under the hood, nicknamed on the forums Hemi ticking.
