Replace the 318 with a Slant

My 2 door,king cab, 2 wd RAM with the 318 got well over 30 mph + on the highway..it was a very big shock to move to a 06 Ram Hemi 4wd. And my record weight carried (with rear air bladders and 10 ply tires) was about 2 ton. The local chrysler dealership couldn't tell me why it got this millage as well. Went to trade it in to a non chrysler dealership and the sales rep called my a liar. End of sale. ....the box was bigger by 6 inches..you would be surprised how much that made a difference. Unfortunately, it self distructed in a specutactular way @ 170Kms and I sold it for scrap.

It started out a s a long haul 5 wheel rig..the rear gears must have been changed but it felt really powerful and not a slug carrying 1000 pounds and pulling a 25 foot trailer.

I would think a /6 in a 3/4 ton would be underpowered and end up costing more..
