Amen. If you can afford an engine built that well, spend a few bucks to see what it can do on a dyno. Rev it to ~9300 the first pull, then look at what numbers it can do. If it can't make power over 9k, there's no point in reving up there. Those astronomical revs only wear the engine down faster anyway.
