List and questions for a carbed 5.9 magnum swap

Thinking about swapping a 360 magnum into my dart, I'd like to put a 4 barrel on it, keep the serpentine setup but remove the a/c and power steering. I have lots of questions about what I do and dont need.

Do I need a new alternator? Some forums say you do and some say you dont.

Do I need a new starter? I may get a mini starter to free up some room for headers.

Will the stock exhaust manifolds fit until I can buy a set of headers?

I think I need a new distributor, correct me if I'm wrong.

Does it have a mechanical fuel pump? Do I need a new one or can I run the oem magnum one?

Anybody got the pulley part number for ac and ps delete?

Its a slant 6 car, will the wiring be difficult?

Thats all the questions I got now, thanks for all the help and opinions.
