What Clutch you 4-speed guys (and gals) running????

I am running a ram power grip setup behind a 1968 Form S 340, bigtime ported t/a headed, 11to1 motor, hughes solid cam with 4;56 gears and m/t indy profile s/s g60-14's. I broke one of the pins that the arm pivots on after 500 miles. sent it back to ram and they fixed it no prob. they said the throwout bearing throw was to far. so we will try it again. car actually moves forward as you take off with the sticky mickeys. I am kinda glad it doesn't hook real well. ( broken parts)
