I'm afraid the engine is starting to go out in my 96 Ram 1500, so I am starting to make plans to rebuild my spare engine and drop that in. What I am wondering is, is the engine from a 99 Ram 3500 Van exactly the same as the 5.9 I have in my truck? I have heard that sometimes these vans have RV cams in them and since I plan to install one when I do the rebuild I am trying to find out if I need a new cam or if the one in there is already an RV cam.
