4.7-Liter Engines: 

The first and only V8 engine to be a part of the PowerTech Chrysler engine family was the 4.7 Dodge engine (also known as the 4.7 Jeep engine). Its valve train includes a single overhead camshaft (SOHC) with a cast-iron block and aluminum heads. The Dodge 4.7 engine had a compression ratio of 9:8:1 and it utilized 2 valves per cylinder in all applications. It is to be noted that in 2008 this engine saw a major update with dual spark plugs per cylinder, upped 9.8:1 compression, a more aggressive camshaft, a larger throttle body, and a better intake manifold. It should also be noted that there was a high-output version of the 4.7-liter Chrysler / Dodge engine with the designation 4.7 HO.
