What is a valeo clutch rated for?
 

Hi, I bought my camaro with a clutch with numbers "167385" on the clutch disk and "382109 DO" on the pressure plate. They both have "valeo" stamped on them and it drives like stock but it is a fully built 383 stroker motor, supercharged and has racing slicks on the back and the clutch has never slipped, so is it possible that my clutch is stock??
It looks stock, not colored any crazy color, it doesnt have pucks, its sprung and it is made by valeo which i thought only made OE clutches, but i don't think there's any way a stock clutch could hold 550whp.
So since i have my car apart, should i go ahead and get a better clutch? because i really don't wanna put it all back together and then the clutch start slipping soon, then have it back on jack stands for however long (I don't have enough money to have a shop do it).

Thanks!
