this needs to be in the 1st generation section, i will move it for you
and ill answer your question, in order to to an engine swap from the 4.7 to the 5.9 you will need the following (at a minimum)
3) wire harness
5) i believe the engines use different mounts, so you need to figure that out too.
and about your oil pump problems, have you been keeping up w/ oil changes? have you been putting in new pumps? i only ask bc iv kept up w/ my maintance and have had exactly 0 issues out of my 4.7, and i have almost 100k miles on it already
