With everything you have listed I would think you will make around 350 to 360rwhp if it is tuned right.
If you want 400 or more get the right heads, cam, and 347 kit and it should be no problem.
As for what you have right now if it is tuned right, I would think you should have around 280 to 300 pretty easy.
420nitro is right on the money.
