700 Hp on NA pump gas

Andrew, I will probably get flamed for saying so, but you don't need 700hp to max out top end very quickly with these cars. Even with your aero enhancements, the wind is not your friend.
Why is 700 the magic number?
If you need a 700hp dyno slip you could probably build a 650hp and still get one that says 700 on some local import tuner's dyno . ;-)
What makes you say that? Just because I am trying to push a reclining refrigerator on wheels through the air? 8-)
I figured that was a good nomber for a well built small block. There are other considerations, I am open to the possibilities.
