That is good advice. I did not even consider that the CTS-V slave cylinder has a shorter travel. I have 2 LS7 slaves on order from O'reilly but they are apparently on a national back order, that has been 2 weeks so far. I will swap the one out in the Chevelle again and just sell the stock CTS-V one. As far as pressure plate torque I never heard that one before. It is critical to torque them evenly and in a criss cross pattern but once the plate contacts the flywheel I would think that over tightening them could only break or compromise the fasteners.

Where is your pedal engaging at ? I just know that the monster had about 1/4 in. Shim with I don't know what slave in there set up (purchased car that way) and the pedal is at like I said 1/2-2/3 let off. The con VS the LS7 was the amount of force it took to push the pedal, not a deal breaker. Good info as always with trials and tribulations from the fuzz.

The earliest hint of clutch engagement begins at 1/4 (letting you manage stop-and-go situations) and the clutch is significantly engaged at 1/2. Complete engagement is about 2/3-3/4 of total travel. The last 1/4 doesn't do much.
Did I mention that I changed my plans for the clutch to succeed my current LS7? For a while, I thought I was going to go with the $650 multi-friction F1 Racing setup that's rated for 625/578 crank ($450 if you have a flywheel), but I ran across a set of 800 and 1000 crank horsepower McLeod RST clutches for $720 and $900 respectively that might go well with my 418 CID LS3 and TVS2300 next year. Linkage below--I'd be interested in anyone's opinion of these clutches.

First one is organic, second rated for 1K HP is ceramic and not rated for racing but street, I would be Leary.

If you look at the RST/RXT kits and some of the user-produced installation guides, you'll note that these things are much narrower than a traditional clutch, which is why each kit includes an adapter plate for standard size flywheels.

I'm interested if you still have it.. As long as it's the correct parts. ( I just asked a guy about one recently and it was a take off from a crate engine, but didn't have the right flywheel or something)

If you have the coin, this clutch setup should hold your supercharged 418 LS3 pretty easily.

When I was looking into the RST, I learned that it drives pretty much like stock, with a softer than stock pedal and that it holds really well. Downsides I read about it were some light chatter and some rattling noise when in neutral, believed to be coming from the floater plate. I was very close to getting it myself.
Also, the general consensus is that if you are going to track your car often, to go with the RXT.
