The new ZR1 clutch. I read that the new ZR1 is going to have a twin disk so I got to thinking is this going to be the next "best" clutch to use in our F-Bodies? I'm assuming it will be very streetable and if it will hold 620 HP it should be the perfect street/strip setup. Any thoughts?

It will never work, and here's why:
Source: http://www.vetteweb.com/tech/vemp_07...ils/index.html
Nestled inside the cylinder block is a forged steel crankshaft that delivers the LS9's 3.62-inch (92 mm) stroke. It features a smaller-diameter ignition-triggering reluctor wheel and a nine-bolt flange - the outer face of the crankshaft on which the flywheel is mounted - that provides more clamping strength. Other non-supercharged 6.2L engines, such as the base Corvette's LS3, have a six-bolt flange. A torsional damper mounted to the front of the crankshaft features a keyway and friction washer, which also is designed to support the engine's high loads.

I felt the same way 
GMPP would stand to make a lot of money if they made a dual disk clutch like this that would work on the older Gen III and IV engines...it would be perfect for 95% of people out there doing moderate performance builds.

I wonder if the clutch and pressure plate would work with the LS2/ LS7 flywheel since the LS9 flywheel definately won't work. I guess we'll have to wait and see. I hope it will because I think it would be a great clutch at least on paper.

That could probably be done but I don't know if I would want to. I think that could lead to several problems but that's just my opinion. I am sure that someone will either try the crank in our engines or the best case would be that the clutch and pressure plate will bolt up to the LS2/ LS7 flywheel. I don't think that GM would design a new engine that wouldn't at least have some interchangablity with previous LS motors. JMHO.

Does anyone have pictures of the ZR1 clutch?
From looking at the ZR1 flywheel picture, it looks like a flat flywheel, similar to the LS1 flywheel. Not like the stepped LS2/7 flywheel.
I bet 50 bucks that the twin disk will bolt to an LS1 flywheel. If not, it would be nothing for a machine shop to drill new bolt and dowel pin holes.

I know this is an antique thread but is this an option or just silly crazy talk?
