Cylinder block and reciprocating assembly details

The LS9’s aluminum cylinder block features steel, six-bolt main bearing caps, with enlarged vent windows in the second and third bulkheads for enhanced bay to bay breathing. Cast iron cylinder liners – measuring 4.06 inches (103.25 mm) in bore diameter – are inserted in the aluminum block and they are finish-bored and honed with a deck plate installed. The deck plate simulates the pressure and minute dimensional variances applied to the block when the cylinder heads are installed, ensuring a higher degree of accuracy that promotes maximum cylinder head sealing, piston ring fit and overall engine performance.

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.

Attached to the crankshaft is a set of titanium connecting rods and forged aluminum pistons, which, when combined with the cylinder heads, delivers a 9.1:1 compression ratio. This combination is extremely durable and lightweight, enabling the LS9’s high-rpm capability.
800hp on stock internals?

I don't think the added 250lbs is a big deal, when you factor in additional 115hp. Supercharger/ intercooler, additional fluids and re-balancing the car are all new weight factors.
The weight of the car is now the same as a 911 turbo, Viper etc and supercharged hp is > N/A HP. The ZR1 is going to pick up huge average HP gains throughout its insane 6600 RPM redline.
Can't wait until they test it, hopefully it will be tested against the 09 Skyline, and the BLUE colour looks amazing, in my opinion.

Oh yah almost forgot to say, i'm suprised they are using a Roots style supercharger than a twin screw for example. Yes it's a bit more expensive, but overall it's not going to make a huge differance.
Lastly, dont you think an ultimate road test would be
ZR1 vs Skyline vs Super Snake?
