WOW! New from Chrysler new, or rebuilt motor new? You should list them in the for sale section under All Hemi motors. You should be able to get the one you're keeping to be able to run in your wagon after you spend 4 to 5 more grand. Headers and motor mounts will be about a grand. Wiring harness and ECM from Hotwire will be close to 2 grand by the time you get the drive by wire stuff. New gas tank with an in tank pump will be close to a grand. Since it's a B-body, you might get lucky and be able to use Jeep Grand Cherokee exhaust manifolds to save some money. If your wagon has power steering, and you want to keep it, you will have to swap to a GM pump that won't blow the guts out of you PS box. You could call Bouchillon Performance in SC, and talk to them about the swap. They sell tons of stuff to do it, and know all the tips and tricks from experience. Good luck with the swap. Looking forward to reading about the progress.
