Considering a Torqstorm for my 225/6

Hey all, thinking about adding a Torqstorm blower to my 225/6 in my '67 Barracuda convertible. Current setup is a Clifford 6=8 package (cam, headers, 4 bbl intake) with an edelbrock 500. Wondering about a few things:

1. Do I have to pull the engine to get the Torqstorm on?
2. Would I have to do any modifications to it internally to handle it?
3. Would I have to do any modifications to the engine bay to fit it?
4. Would I be able to keep the power steering?
5. Would those who have used this setup recommend it? Ie, is it really worth the 3k?
6. Is it something that a novice can bolt-on, or would it require serious skill?
