Just how hard is it

I'm a few years into the swap. It's not that its hard, its the fact that you are putting a modern engine into a classic mopar. So in my case I started replacing everything else. There was no was I would put in that motor with the rest of the drivetrain being "out dated" or sub par. That and the little problems you run into with Fitment, would make me suggest bringing cold beer and a lunch. You might be there a little while. Just my .02
