[Fullchat289]

I, like Bob, are an Engine-nerd. I understand that the stresses seen by a clutch assembly and flywheel are directly affected by engine speed through the velocity component being squared. I understand that this simple fact is why stresses are amplified with increasing engine speed. What I don't understand is why the OEM components are understood to be unsafe. Why do we need specially approved bell housings and flywheel/clutch components? I've heard the near death experiences, but why is it that if an OEM set-up is engineered for a 6000 or so red-line, and I build a 289cid for the street that will occasionally hot-dog it to 6750 or 7000 to scare the piss out of a local boy racer, do I need to buy all this special stuff? I suppose that when it's all done and dusted, a lakewood bellhousing and some approve internal bits are cheap insurance compared with prosthetic legs. Is this everyone's thinking???

Thanks!
