need help in sourcing the correct rated clutch for a

tuned pinto, lightened, vulcan 2 head etc,
prolly about 150 hp.
need somthing sensible for road use. and occasional tracdays...

now have a very high pedal and loads of judder..me thinks not going to last long..

Std one will be fine according to the books i have read. The std clutch is quite heavy duty anyway and is fine for all road engines.
