Haha, I'm still running a replacement LS6 clutch I installed way back before all this LS7 stuff came out (about 2006 or 7) Darn thing still works fine with a mild 370 rwhp and many drag strip passes and my wife driving it daily. 70,000 miles on that clutch now.
With bigger plans for the engine I'll likely switch over to Centerforce, a brand I've used for decades and their main manufacturing plant is 7 miles up the street from my house I talk to those guys on occasion when we bump into each other.
