Help Needed With My Thermal Design Project - Designing a Turbo System for the Slant!

For those of you who don't know, I am a senior level mechanical engineering student and have been assigned a project for my Thermal Systems class. We have to design any kind of thermal system that we choose and I convinced my group to design a turbo system for my 74 dart with a 225 /6 & 904 transmission. We don't have to build it, just design it. However, I do want to be realistic with the design so that, if I choose to, I could actually build the system sometime down the road. Everything will be designed using a stock, carb'd engine using a 4brl intake and carb.
We will also be using an intercooler. I have a really good general idea of how the system should work, but as I dig into the details, I'm sure a lot of questions will come up.

For the people who have done this and have turbo build threads, can you please post links and pictures that you would be willing to share? Anything that we use for our presentation will be given credit. Pictures will be a huge help since we are not actually building anything.

Now for my first round of questions...

1. How much boost can the stock slant take while maintaining reliability?
2. What makes a "blow through" carb different from a regular carb and what would be a good one for a turbo 4bbl slant?
3. How fast can I safely turn the stock motor? Everything will be stock for this design. Cam, crank, pistons, heads, etc...

Thanks in advance! We have to make a 20 - 25 page report and a powerpoint presentation. I will be posting all of it after it is finished.
