Okay here it is....my 5.0 just ate the teeth on my stock flywheel. I need to get a new one. I have a big question..why are some 50oz balanced and some 28oz balanced? can I use either? if I can what are the benifits? the other question I have is about a clutch...I have a center force in it now but with having to drop the trans and flywheel I firgure I will switch the clutch (not sure how many miles are on it ) How are the King Cobra clutchs? Please Help.
