Hi tech Cobra I was not trying to be a smart@$$ again, I just went by the reading. The lakewood bell housing weight almost 50 pounds. You said your was very lite. There should be a label on the bell saying SFI certified and a date for when it is to be retested. We go through this in the NHRA racing. I think it's every 3 years. If you call Quicktime ,I'm sure they have an answer for this. I hope it's just a poor description of a part and not a trying to get over on the public game. Rick L. P.s I am gald it's steel, but I am thinking that it's more designed for a multi disc small clutch like a 6-7" Tilton assembly. When they blow there is alot less change of the major damage than when a stock size clutch blows. Sorry for questioning your build.
