4.0 to 4.0 High Output swap
 

first time jeep owner any tips and or tricks on the 4.0 to 4.0 high output swap would really help.
Thanks

hope your not doing it for the horsepower difference

Yup, I'm doing the same swap it's been slow, been a lot of trial and error. You'll need to swap distributors, flex plate.. I might be forgetting something but best of luck to you! What year ya swapping into. If ya have any big break throughs let me know or questions I'll see what I remember

There is a write up in the write up section that may help.

im completely pulling my 4.0 and swapping the wiring harness. the dit should work form the high output. i have a 90 cherokee and putting a 94 h.o in.
