Sounds pretty good to me, I dont know a whole lot about big chief stuff, but it seems like it should work well to me. What are you planning on rapping it to?, I think it would probably make power to 8000 min. Also, do you know if that is the most compression that you can run? I would run as much as possible with that setup, and I think you can run 15:1-16:1 on alcohol.

That's close to what I intend to build, after I win the lottery. The only thing I would change is the headers. 2 1/2" primary tubes with those collectors might fatten and flatten the torque curve a bit. Not that it really needs it.
