RE: horsepower estimate
 

get on a dyno... seriously. Nobody can honestly make an accurate guess as to how much power someone is putting down just by looking at mods. A dyno is the only real way to find out.

And as far as the cams go, my guess is the stock redline. Stage I cams don't require upgraded valvetrains, which tells me you don't need to rev any higher than stock.
