Just curious if anyone one here has done a cummins swap on their jeep I would love to put one in my cj7 and was just wonderin how many hours someone would have to put in to make it work and what transmission choices would I have right now its just a dream but I still want to know thanks in advance
 

Hours to install.. Lots.
This is not a weekend swap, you will have to make motor mounts, cross member, new fuel lines, intercooler lines (if applicable) swap your brakes from vacuum assist to hydro assist, etc...

For trans, depends on what you are going to do with the jeep
for a Daily Driver I would run

built 700r4 auto
NV4500 man

for a trail rig

TH400 auto
sm 464 man
