Michael, I'm in the same boat you are with an M725 and no engine right now. I bought a bellhousing that is supposed to fit a T-18 tranny and a Jeep V-8, but doesn't look like it's going to. If you can find a Jeep 64-67 J-3000/4000 with a stick, or a 72-79 Wagoneer/Cherokee/J-series with a stick and get the whole thing, from bellhousing to xfer case, that would be the best, as you could then move it all to the 725. If not, then you can use a Jeep 360 motor IF you get a flywheel ($100) and a bellhousing ($50) and clutch parts (?), etc. I have decided to bide my time and find a whole setup, engine/tranny with or without xfer case, so that I can move it all over in one shot.

I am currently negotiating for a Chevy 350 w/700r4 tranny and xfer case. Then all I should have to do is new support brackets for the tranny/xfer, maybe have the driveshafts modified, and get a floor shifter for the tranny.
