I'm guessing by your lack of answer on the second part that you don't actually know your gear ratio then. Regardless, before you start amping power up, you need to address your first hurdle and that is transmission. The RFE is pretty much at its limit with the eagle 5.7. If you're looking at forced induction at all then you better figure that one out first (FYI there is no reliable long term RFE built to handle more power).
