6.4s are a little better then a 6.0 but at about 100k they are burning up turbos and dropping valves and a replacement 6.4 will run you 15k on up depending what you get. However with a sparton or h&s tuner they make crazy power.

With only a 3 year market on them I would hate to have to get parts 10 years down the road
