Stock Clutch strength

What is the maximum a stock LT1 clutch can handle? rwtq and rwhp

I don't know if there is a 'set' number that it can handle, but I have a stock clutch and it holds a 5500 rpm clutch dump on slicks with 4.11's. (granted I have a stock motor, but it sure is violent lol)

I'm running 346 rwhp 338 rwtq and have no probs althought the clutch is fairly new. The weak part is the center, it tends to crack thats what took out my clutch when the motor was still stock.
