One of the classic ways to travel the United States is in a motorhome, and one of the most classic motorhome engines ever made is the Dodge 440 by Chrysler Corp. The Dodge 440 engine can be found in many 1970s full-sized motor homes, especially the popular 1974 Winnebago. Quite a few of these are still on the road, and with a little work, you can get that engine running smooth as ever.
