Great looking car! :thumbsup:
Looks like it's been really well taken care of. Love that the top is painted instead of vinyl, that will save you a lot of rust repair later!
As for your questions-
1. A 360 is a great engine. Biggest drawbacks are probably the cast crank and 360 specific external balance, but neither of those are really a big deal. Pretty much everything else about it is a plus.
2. Yes, you can totally swap on a Duster front end. As nice as that car is though, I think I would leave it alone! Painting the new bodywork to match isn't cheap, and it's definitely money you can spend elsewhere. But, if you really want to swap it, you'll need everything from the doors forward that unbolts. Fenders, hood, hood latch support panel, grille, grille support, bumper, and brackets. Since your car is a '74, you might have a shock mounted front bumper, which can be complicating. But it kind of looks like you've got a standard bracket bumper, which means any standard mounted Duster bumper that matches the front clip should work.
I did the opposite swap, I went from a '74 Duster to a Dart front end.

3. Forced induction is not my area of expertise, there are no doubt options for the 360, for your Dart specifically is a different story. Keep in mind if you have a stock engine build you have cast pistons and a cast crankshaft, so, you'll want to go easy on the boost until you get things sorted out.
And finally, get rid of those lift shackles!!! They're not particularly effective, not exactly safe, and in the long run will ruin whatever is left of your springs. Overall, they give you LOUSY handling. If you like the ride height as high as it is in the back, you'll need new leaf springs with a higher arch to do it correctly. ESPO is a good source, they sell +1" and +2" springs for the back. If you don't want the back end of the car jacked up '70's street freak style, just put a stock set of shackles back there.
