Take our advice and choose neither! You will do much better if you go with 7.3L powerstroke engines. However, if that’s not an option, you should choose 6.4L because it clearly has better features than 6.0L. The only place where it loses is the repair expenses. If you can come to terms with that, 6.4L is your answer. Otherwise, if an average powerstroke engine works, 6.0 will work and let you save money when the time for repairs comes.
