Reply to "Flywheel and clutch"

To answer your earlier post, the stock 3-finger clutch is fine up to maybe 500 bhp. Changing clutches is only done if
-A- your OEM is slipping at high torque,
-B- the effort required to push in the pedal is too high for comfort; in that case a diaphragm clutch is easier to push in and has about the same holding power as a 3-finger.
Or -C- the disc is worn out or pressure plate is broken.

Note that if changing flywheels, most aftermarket units are drilled for multiple patterns while the stocker is only drilled for the stock Long 3-finger. Redrilling and tapping is a job for pros. I'm looking at a nice Weber cast-aluminum flywheel in a shop, in which someone stripped ALL the clutch bolts out while installing the assembly. The flywheel is now worthless. Torque wrenches are required!

If you're going to that much trouble, I also suggest changing the throwout bearing AND the pilot bushing in the end of the crank. Reason is, they wear out too and changing them requires the trans to come out, so most of us do it whenever the gearbox is removed. Parts cost is minimal compared to the labor required to change either later on.
