Well Keith you are gonna spend a bunch of money on that engine anyway..For just a bit more go first class and put the complete 4.0 in there..
Look around and see what a donor vehicle would cost that already has everything you'd need in it.
Although the components you mention can be made to work..they do not FIT each other perfectly. There is a lot more to be gained by putting everything that does fit in there at the same time.
