Subject: '94 LT1 clutch, flywheel, etc. by SJW on 2007/11/1 20:33:09 Hey, everyone. I need to pull my '94 LT1 down for some maintenance items this winter. On the docket are: Clutch Shifter boot Tailshaft seal (and possibly bushing) for the ZF-6. ZF-6 lube change. Corsa exhaust (to replace the B&B that's on the car now). I'm seeking advice about the clutch job. Questions on my mind include: 1. Flywheel choice. I'm not a big fan of dual-mass flywheels. Their cost and susceptibility to premature failure leave me less than thrilled about buying and installing one as a replacement. I know that I do not want an aluminum SM wheel, but I've heard talk of steel single-mass flywheels that can be used instead. My understanding is that minor machining of an F-Body steel single-mass wheel can make it a direct bolt-in replacement for the Y-Body DM unit. Can anyone offer any rock-solid factual info about this? Also, just how bad is the gear rattle likely to be with a steel SM wheel in a '94 LT1 car? 2. Clutch choice. OEM? Aftermarket, and if so, which one? Upsides and downsides to any aftermarket options would be most useful to know. 3. What are the issues associated with balancing the clutch/flywheel assembly? How is this affected by either staying with an OEM DM unit, or switching over to a modified steel F-Body SM unit? 4. I'm aware of the C-Beam plates, and they seem like a wise expenditure. Is there anything else that's useful to know beyond what's addressed in the FSM? Many thanks in advance for any insights. Live well, SJW |
