Well get out your Pom Pom's South Bend Clutch has a new full Organic 13" clutch that is as smooth as stock and will hold some pretty good power. I have it in Cliffmans truck now and it is equipped with DD III's drag comp and a 16 housing dynoing in at 410hp with no slippage. I think this will be a great clutch for someone in the 350 to 375 hp range just to be safe.
