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

This is the 2nd SPEC clutch i've ran. First one was a Stage 2 in a 450hp AMC powered sand jeep weighing 3,500lbs. It was a diaphragm style kevlar clutch. I ran 35" tires with 4.56 gears on the street and did MANY big burnouts on the street not to mention lots of sand drag racing running aggressive paddle tires. That clutch was nothing short of outstanding. Never any slipping issues and zero chatter. It felt like a stock easy clutch. Because of this, i'm running a SPEC stage 2+ in my 69' Dart. I understand why many people don't like diaphragm clutches and swear by B&B clutches, BUT I can honestly say these SPEC clutches are awesome and worth every penny. Clutch technology has came a long way and SPEC proves this no question.

I’m a little weary of Kevlar because of a poor experience I had with it drag racing with slicks on my 2.2 turbo Daytona car years ago . It was excellent on street tires but with slicks at the track it slipped and once it slips it won’t recover.
