nothing is wrong with spec, 99 percent of clutch concerns is bad install.
I have a king cobra and it's very good..
I also highly recomend a new clutch fork and pivot ball and a TOB if you clutch kit is not coming with one. trust me on this I am a ford tech by trade and I have seen people have a stiff pedal because they negected to replace the pivot ball when they are bad or wearing out. the way I see it both of those parts is less than 40 bucks so it's miney well spent to replace them when you already have the trans down.
