King Cobra clutch hp?

I do not have any idea of how much horsepower it can handle, I just wanted to ask a question about the clutch. I have the same clutch. The clutch was installed 400-500 miles ago and Iam still getting clutch chatter starting off in first during normal driving. Will this ever go away or is this a normal characteristic of this clutch?
 
hah, i have another question... what year stang do you have that it's 3400 lbs? this is a 94-95 thread so i'd venture a guess that that is what you're driving...but i thought that our cars(verts) were a couple hundred lbs heavier....if it is what did you do to get it to 3400? and i'd venture a guess that you wouldnt want that clutch with anything more than a h/c/i package on a 302 block(im guessing 350 rwhp or less since i see clutches claiming to be better than the king cobra clutch able to handle 400-450 rwhp) just a guess tho, i dont know for sure
 
I got some chatter in reverse for a little while but that was all. Did you resurface the fly wheel?
