There not that bad on gas. I would think it wouldn't be any worse than a 5.9. Our 5.7l Hemi in the Magnum gets about 20mpg mixed driving and that is with me punching it just about whenever I can.Karas3434 said:oh hell yeah a 6.1L would be crazy under the hood of a dak. as long as you dont mind like 6mpg!
Judging my 7200 lb. 2001 Quad cab short bed cummins 6 speed with everything i have done to it, that would be a very beautiful idea.dodgedakotamccoy said:that would be sweet as hell in a dak i mean 8.0L, but imgine this a built cummins in a short wheel base reg cab 6spd dak
