Dual Disc clutch for the slant 6 from Ram.

You V8 guys just don't understand slant six clutch issues.
Any HP slant will eat a clutch in a short period of time.
The last good slant PP was the Weber 9.5 that was built to 340 spec.
It had the good springs and levers, but they have been gone for years.

The dual disk is just the technology that clutch builders have been moving to.
