I would hope to see 70 to 80 HP better than it was, and I think it should have about 500 at the wheels at that point when it's done.

Edit, to be more detailed about it....
60 to 70 from the head work
9 to 13 from the CR increase

And though it is an oversimplification, I am talking about adding that to the 425-ballpark number that was observed earlier, which should put it pretty close to 500rwhp at the end I would think. Maybe more.
