30+ thousand miles and going strong at 900+ flywheel HP seems fairly reliable to me. Just saying...

You have no Idea. Remember, you've only been at that power level for 5000 miles.

You're right about that power level for 5000, but I have been WELL over 500 rwhp since 2,100 miles. 580 rwhp is roughly 670-680 fwhp...and my current mileage is 67,6xx. I think 65,000 miles at near 700 fw is quite a testament to the strength of these engines.

What he wants = +700 rwhp = not safe or reliable for any type of long term timeframe. If you don't care about having to rebuild your motor in a couple of years, then yeah, go for it.
