Clutch Recommendation

340s making too much power, or maybe traction is too good. Clutch is starting to slip on launch. Maybe clutch is worn out, dunno. It engages less than halfway up, so I think it is OK, just need a stronger clutch. What would you guys recommend for a 340 to have plenty of headroom for a higher power rebuild say, up to maybe around 400hp some day? Money "is" an object, but I want something good, best value so to speak.

Tks...
