[Fast67VelleN2O]

I run a Centerforce dual friction clutch in my 67 Chevelle with a M20 660 case muncie and a 12 bolt with 3.73 gears. Very good clutch, soft pedal, and I haven't broken anything yet with about 25,000 hard street miles. I launch the car on slicks at the track at least once a month and still no issues.
