I think as far as the camshaft is concerned, you should just contact a cam manufacturer and have them custom grind you a cam for your application. I don't know a whole lot about blown motors, but I'm pretty sure cam grind is very important. Once you have decided which size blower you're going to use, you should contact Holley, Edelbrock, Jet Performance or some other expert in the induction field and ask what they recommed using for a carb (or carbs).

Get the 8-71. You'll also need two 825s to feed it. In my experience, your cam choice will likely work. Blowers tend to make cam choice less critical. If you want optimum, then get a custom blower grind.
