Don't know the stocker numbers, edmurder; but from what I've read from other posts here (if I remember correctly) a really hot, well balanced 235 can give you 175-200 true HP. I'm guessing peak power around 3000-3500 rpm, after bumping up the cam duration.
While that may not sound particularly impressive, 200 HP is probably a 75-100% increase over stock. If you want more power go with a 261. It's a no-mod bolt-in fit.
