Nope sorry,. The SB Dodges(318,340,360) all use a different bell housing from the Big Blocks(383,400,440). Also the 318,340,and 360s are all balanced differantly and thus require different flywheels/tourque conveters.
4WD BB Dodge auto trannies are extremly rare, Manuals are even more scarce. Two options:
1) Probably the easier on. Take the money you would have spent on a 440 conversion and build up the 360. I did this and was happy with it. I just do trail riding and mild mud slinging so went for more torque. Unless you are mud racing you will probably be happy with this.
2) Get a 2wd tranny for some old '70s Chrysler boat with a BB and have the tailshafts swapped over, bell housings are integeral to the case. If you do this try to get a whole engine/tranny combo so it will all work together. Not sure about rad. All ectronics should swap over. Upgrade to the larger 100amp alt at the same time. Dodge also used two sizes of starters, small and big. Get a big one I believe they are interchanble between SB and BB and auto and manual.
Good luck!
