LS9 (pics inside)
Is it just me... or is it becoming as hard to have a badass motor as it is to have a badass computer? Everytime you get the newest and greatest, something else stomps you in the mud.
Nice motor, but personally I wish they'd stick with the LS7. Anyone can slap on FI and make gobs of power. But GM has been one of the few making serious power NA. Turbo on a V8 would be interesting to see on an LS motor.

older doesn't necessarily mean that something is not still badass for what it is
Did you just hear that huge noise? That was the sound of most of the C6Z owners putting their cars on autotrader so they can buy the "best of the best" Corvette for bragging rights. lol
Don't laugh, it happened in 2002 also

50% or more of Corvette owners are morons. They can't change a spark plug, but they can open a (fat) checkbook.
I used to own a Corvette, but when I learned how to change plugs, I sold it.
I didn't fit the image anymore. Plus, the local Corvette club said my ***** couldn't be longer than about 2". Since my ***** is a mighty 3", I had to sell the car. 
LS9 intake manifold swap 
No, it's a hand built motor at the Wixom (sp) plant where this LS9 motor will also be built, the LS7 wont make it in to any sort of mass produced vehicle just due to the cost, expensive enough to put in the C6 Z06s, its also supposed to phased out by 2010 or so.

Im with the other guys, Id love to see what this motor will do with a tune and a pulley 
Not that 650hp isn't enough!!!
Most of these cars will be owned by people who can't/don't know how to drive a car with this much power, that's the grim reality of it all

if somebody buys a car with a LS9...they damn sure are going it for a reason.

The twin-plate 260mm clutch has more than enough capacity to handle the LS9 prodigious output while requiring the same or less effort than the single plate 290 mm unit in the Z06

Displacement Drops
The new LS9 exceeds the LS7 in every area except one, displacement. The main reason for the drop in displacement was strength. GM's plan for the LS9 included a supercharger and they felt the 427 cubic-inch block wasn't strong enough to reliably hold up to the intended boost. Instead, a beefed up 6.2-liter LS3 block will be used. Starting in '09, all 6.2L blocks, including truck blocks, will feature this 20 percent increase in bulkhead strength. According to Tom Reed, of GM, "All the blocks benefited in '08 with a 20 percent increase because of the LS3 improvements. Therefore, since 2007 the bulkhead area strength has increased 40 percent. Something to keep in mind when the 6.2L blocks start showing up in the bone yards, way down the road." The 319-T5 aluminum block, with forged steel bearing caps, will also be deck plated, bored, and honed. The LS9 will also feature eight block-mounted oil squirters. These squirters will keep chamber temps down and lessen drivetrain noise. This is the first time GM has used oil squirters in a small-block application. By sharing the casting across the LS3 line, costs will be kept down.
