Is this a good idea?

Hi everybody! I've got a 75 dart se that was purchased brand new by my grandmother. I inherited this car 6 yrs ago, did some bodywork and repainted. It's a super nice car and I never want to get rid of it. But I did some mods to the 318 and it's just not working for me. I also have a 68 383 that was in a Newport my dad owned since 1970! I drove that car for many years but eventually pulled the motor because of rust issues. Was a great engine and trans. So I'm thinking of buying a schumacher swap kit and putting the 383 in it. My dart already has 2.5 inch dual exhaust and disk brakes so I think it's a logical swap! Just want a nice driver! Kind of a sleeper. Is this swap as easy as it sounds? Can I retain my power steering?
