96 dodge 5.9 out of a Ram 1500 with 40.000 miles
check out magnumswap.com lots of info on belts and oil pans etc. If you stick with Magnum pulleys and timing cover, you will have to run an electric fuel pump on frame.
As far as a cam, you will get 20 different answers from leave it to .680" roller. If sticking with stock heads I would keep it under .460" lift with stock springs. We sell a regrind for $179 that is just a touch larger than the 5.2 cam and a nice step up from the tiny 5.9 cam. Its .450" lift and 203 @ .050. You could go a bit larger on duration and 110 instead of 112 LSA but you are about maxed out at .450-.460"
