I asked this question a few years ago... it's probably in the archives.
For what it's worth,, I was advised not to take it past 6k in stock form. However, I am sure you'll be doing a rebuild/upgrade, and including an HD billet flexplate and a scatter shield. I think those are steel planetary gears, not aluminum, so watch out!
