Yet ANOTHER Hemi swap, but need input

so, like the other post, decided to change direction and do a Hemi swap in. I’m sure most of the answers to my questions are in various other post but having difficulty putting all the comments together.

I have a (now) stripped down 1974 Dart Sport, factory V8 cross member (Spool type mounts I think?) with PS and PB.

Questions are this:
What is a reasonable $ for a low mileage 5.7 for drop in/plug and play excluding all the necessary electronics?
Can I use my stock K member knowing that eventually (no time soon) I will change it out?
What mods are needed to the steering column (it is floor shift if that matters)?
Can I keep the current PS / gearbox just change out the reservoir for clearance?

Shoehorning it into the car does not concern me. It’s more the K member, PS/PB, and column that I need input on....

Thank you in advance!
