Need Info on slant 6 to V8 swap

Hi, I just picked up another 66 dodge dart gt. this one had a slant 6 w/ power steering. I have a 273 hi po I want to put in. Here are my questions:

1. Do I have to change the K member? I hear you can buy a motor mount kit from Schumacher instead?

2. Do I need to change the torsion bars?

3. It has 9" brakes, what do I need to change to 10" drum?

4. Is the steering box the same as a V8, I want to send it to Steer & Gear to have it rebuilt cuz I found a floor shift column and want to make it auto/floor

5. Do I need to find a V8 PS Pump or will the 6cyl work?

Heck, that enough for now.. if anyone can assist me that would be great! Thanks for your time
