The Paxton is the most compatible with the Cobra setup. A small amount of boost (4-6psi) should be all you need. You'll definitely have to retune your EFI. And you may need to look at your fuel delivery (pump, lines) to be sure they can handle it.

I would caution you about adding too much horsepower. Cosby's 200 MPH routine was a documentary. Too much horsepower turns a Cobra into a death trap. You probably have a pretty nice streetable car. It wouldn't take too much more HP to turn the car into a "rear end breaks loose at the drop of a hat" - or any downshift or any upshift. My car had a Roush 427IR that engine dyno spec at 550hp, with about 500 at the wheels (I think their 550 was conservative). It took great care to not break the rear end loose.
