Hi tech cobra Quicktime sells 2 bellhousing for the FE motor. One saids it passed SFI testing but doesn't say CERTIFIED. The other said nothing about this at ALL. What is the bell housing made of? Aluminium? Titanium? Be careful with this. The other thing is to check your bell housing for being centered on the motor. I was told the same thing about nothing to worry about. The Lakewood was .038" out of center. I would double check with Steve about this whole thing. If you go to their website and lookup your bellhousing, the wording is questionable. If you are running a small multi disc clutch like dirttrackers, this will be maybe OK, but if you are running a 40 lbs flywheel and 11" clutch, I don't think this will save your legs from an schatter clutch assembly. This bell is for lite duty usage and racing. Just my opinion. Rick Lake Ps I have seen clutches and flywheels come through roofs and windshields. Feet and leg lose is about being lucky. You might want to rethink this.
