Pick a clutch.....any clutch

What Centerforce? I ran their dual friction set up years back. It's pretty brutal on parts, if you have some power. Like a friggin light switch, on or off and no in between.

Never failed me though, but I don't like the weights.
I'm pushing near the power you have and run the dual friction center force. Had to make a pivot bracket out of 1/4 plate because the stock one cracked over and over. I run a Lakewood bell, the pedal feels great...you just need to get used to a performance clutch, stock is was smoother for a reason, they don' have the holding power.

2nd choice Southland clutch, great pedal.

Btw hard pedal is a the Hayes strip clutch, lasted 6 months on the street and one hell of a hard pedal...made the action harsh and trying to slip it ...killed it.
