Drivetrain In need of new clutch for 500-550hp

So I got my nitrous system ironed out and the clutch began slipping terribly on first test... I suspected that it was already slipping NA.
What clutch would you guys suggest??
I’m clueless on who makes a good one for my application... motor is just a 306 but made 345hp to the wheel when tuned so I guess about 390hp at flywheel?? Still T5 trans, I have a throttle body nitrous plate but it won’t see more than a 150 shot.... I want a good one, but I don’t know anything about the dual discs deal and doubt I need one but thing change so fast I figure my best answer will come from you guys. Thanks in advance!!

Thanks, I’m going to upgrade to the G Force T5 which is rated at 600hp/500ftlbs. So that should be plenty.

I’m leaning towards a dual disc clutch, although that may be overkill, perhaps I won’t have to worry about overpowering it at the track... at least I believe I “overpowered” the existing king cobra clutch anyway because it was fine and after not spraying it for a while it just started slipping like crazy... I’m no expert by far...hopefully I won’t find it oil soaked... I guess that could happen??
It sure seemed to go from fine to absolutely done. Again I’m no mechanic but I know it was installed right because I was the helper, saw the whole process
Engine sounded fantastic though!!
All recommendations, advice, welcome please.
