doesn't seem to be any info on this on these boards so I'll toss it in since I am doing it now.
4.6 is relativly straightforward, 258 crank and rods in a 4.0L, silv-o-lite pistons to keep the CR down so she'll run on donkey piss for fuel.
tranny choice was a tf727 from a 1980 wagoneer, tf-2 transgo shift kit
transfer case choice was the NP-229 bolted to the 727, for simplicity of the swap aswell as for the full time option that it offers, for the towing and winter duties I intend to put this truck thru I felt that was the best choice.
Front axle will be a lincoln locked posi-lock D30, the rear will be either a spooled or a LS D44
first problem I have run into is the crankshaft position sensor on the flywheel, solution at this point is to either relocate the mounting bolts on the torque converter, or to drill out the flexplate to take the converter bolts, but that involes relocating the mounting holes overtop of a lip in the flexplate which is something I really am not fond on doing, the flexplate is coming off of a 4.0L - AW4 of the same year as the vehicle it's going into and donor of the 4.0L for the stroker, a 1988 comanche laredo.
I will inform you guys of anything else that comes up later on, I've seen lots of people planning on putting a 727 in an XJ but haven't found anyone who has done it yet, looks like I"m the guinee pig!
if anyone has any information on twinsticking a NP229 (one stick for 2, 4, n, 4lo and the second stick for posi - locked) I would be glad to hear it.
I"m hoping to get a full ratchet shift in it at some point.
the vehicle beiong modded was a 1988 MJ, 4.0L-Ba-10 pegeot 5-speed- NP-231- D30-D44, spring over rear BB front
