86 Cherokee OM617/700R4/NP231
MPG update. Well I just filled up and was very pleased to find the mpg's stayed at 25.7 with the IP change. This is mixed driving to & from work, very little freeway. The power is way up and the trans is shifting better by not having to keep my foot burried. I also noticed the freeway runs needed alot less throttle and showed a lower boost reading at cruise. Can't wait for the next road trip!! O yea, the IP timing is set at 26-27 deg.

great to hear that here is a thread on tuning the pump good read will be some of what I do for sure

so now a technical question what is the optimum power to weigh ratio mine would be 0.038795779019243 that is a title weight of 3222 and hp of 125

Would there be any problems with using a 2000 Cherokee with this swap? Any chance of using the AW4? I was planning on swapping the rear for a 44 with 4.56 gears and putting 33's on. Anybody looked into using the OM603 with updated casting?
I considered using the aw4 at first, but my jeep came with the tq flight trans so I went with the 700r4. The early aw4 has a stand alone computer, but I think the later ones have it as part of the ecu, so that would make it more of a challenge. I think there is a guy that put a 60X in a Samuri.
