Had you considered trying a stock 3.0 disk? They can take a surprising amount of torque with the right pressure plate. I had one with a Sachs PP that easily withstood 423 ft-lb at the rear wheels, and I've heard of them working on engines that have well over 500 ft-lb at the rear wheels. I have a SPEC disk ("ferramic" all-metal, spring centered, full circumference) coupled with a beefed up Sachs sporting clutch. It's crisp and capable, takes modest pedal effort, and relatively inexpensive, but it's heavy and there is some chatter when starting. It's supposedly bulletproof and good for 650 ft-lb (at the crank). I sort of wish I'd tried the stock disk, and I still may, just to increase the friendliness factor, especially given that I have an inordinately tall first gear. But it's a pain to experiment with different clutches, so I'm okay living with a little chatter for now.

Also, not knowing more, I wouldn't necessarily dismiss your problem as a disk-only issue. Any chance the pressure plate was not up to snuff? What were the symptoms of your clutch failure? It might be good to send the whole thing to Kennedy, Centerforce, SPEC, or some other clutch specialist for an evaluation.
