The Dodge 4.7 engine is a 4.7L V8 gasoline engine. The engine was actually made by Chrysler, but it was fitted to several Dodge models. Hence it’s often referred to as the Dodge 4.7 engine. Dubbed as the Chrysler PowerTech engine and sometimes called the Magnum engine, this engine family was initially developed by American Motors Corporation (AMC) but it’s credited to Chrysler and it was made in good old Motor City, Detroit. The engine made its debut in 1999, first appearing in the second-generation Jeep Grand Cherokee. Afterward, several cars from Dodge, Jeep, and even Mitsubishi started using this engine.

There are three versions of the Chrysler PowerTech engine. The first is the 4.7L V8, and then there’s the 4.7L “HO” or high output version. And finally a smaller 3.7 V6 version of the PowerTech engine, which is basically the same engine but with two cylinders removed. There was also a 2008 revision for the 4.7L V8 “HO” engine with a different camshaft profile, new combustion system design, and other upgrades that made the engine more powerful. The engine stayed in production up until 2013, staying in production for 15 years and 3 million units were built. Chrysler has since replaced it with modern versions of their 3rd-generation Hemi engine.
