Best Consensus I've seen so far is
Spec Clutches for the LT1s....
Just pick the combo that meets your HP/Usage goals.
I can tell you I've got 20K+ miles on my Stage II+ and it holds like a champ with stock like drivability.

Since you probably have a few more HP, you may want to go to the Stage III or III+ (Plus is essentially the non-puck or easier engagement material but holds the same power level)
