Because, a GForce will hold upwards to about 1000rwhp. there is no way GM is going to overrate their's just for the sake of being nice. If it holds 600rwhp. I'd be surprised.

I certainly won't debate the ZL1 is stronger than any of the high end drivelines, but it will certainly hold more than 600 whp. When I researched there were no reports of any zl1 driveline failures. I still haven't heard of any, but I haven't been looking either.
I found many ~750 whp cars run hard w/o issues. I'm running just over 800 whp w/o issue (soon to be > 850). I'll admit my car has been in the garage more than at the track (hence the pathetic ET). But I hope to change that soon and will continue to report back on the ZL1 driveline.
So far, holding strong!
