The Dodge 4.7 engine is not a 318. It is a newer, more powerful engine that was first introduced in the Dakota pickup truck in 2003. The 4.7 engine replaced the older 3.9 engine and was available in both two-wheel drive and four-wheel drive models. The 4.7 engine was also used in the Durango SUV, which replaced the Dakota in 2004. The 4.7 engine produces more power than the 3.9 engine it replaced, but it is not as powerful as the 5.7 Hemi V8 that is also available in some Dodge vehicles
