Moral of the story, you need the cam that will carry to 7000-7300.
So agressive gearing needed. Depends what you you do with the car.
On an interesting note, I remember they said porting the FAST lsxr can hurt the results. Id go with a very potent porter or just port match lightly. Or leave it alone damn at that price.
