I'd suggest buying a complete rotating assembly for a 2005 2500 truck with a 6.0 engine. This will include the flywheel, clutch disk, pressure plate, and pilot bearing.

I briefly mocked up this setup with a hydraulic sm465 bell, and everything cleared fine. The reason for the mockup, was to see if any factory manifolds would clear the sm465 slave. The Silverado manifold will clear if you turn the slave upside down and remove the heat shield. The TBSS and 2010 Camaro manifold don't come close to clearing. The F-body manifold clears easily, but is a very restrictive manifold. I'd suggest using headers instead.

As far as I can tell, the ls7 pilot bearing is the same as the 6.0/nv4500 pilot bearing.

At some point I compared a LS engine with a nv4500 flywheel beside a sbc with a sm465 flywheel. The LS engine moved the friction surface 1/8" closer to the block. I neglected to measure the finger height of the two engines side by side. I could, and should, still do this, assuming I can still find all the correct parts for my sm465 clutch pack.

You may need to use an extended throwout bearing, if the clutch fingers are in a different place compared to the sm465 clutch.
