Horse power guesstimations

I am not sure how close the figures are with cam quest, because you can't have all the right parts that is in your motor. I put in the figures as good as i could and depending on which cam you pick, the hp falls between 575-645. The tq from 580-600.
Has anyone tested this system with a motor that has been dynoed?
Thanks for all your input. I can hardly wait to floor it.
