Which Clutch up to 450hp Street car with some drag racing?

There all really good at these low power levels. The difference in the clutch that will effect you directly and mostly is if it is a Borg & Beck 3 finger pressure plate that is a bit stiff or the Diaphragm pressure plate which is very soft in pedal effort but should require the over center spring to be removed. That is a royal PIA by the way.
