notice that says one valve for intake and exhaust, so no 3 valve setup. where are yall getting that this is ls7 stuff on the CTS-V race car? Im seeing it as a different version of the C5R setup, empahsizing revs.

The bigger the better.That way I can buy the bare block and stroke it out as big as possible and make 550-650 rwhp. If I got 426+ RWHP and 406RWTQ out of a LS1 5.7 I'm sure I can get atleast another 100 hp out of a 6.4-7.0 block stroked out.500hp goal....... whats the problem-there are a ton of us 5.7 L guys that make over 500hp at the crank.With all the high tech **** GM has a 500hp engine that passes emmisions shouldn't be a problem.I just want a block that my heads and intake will bolt up to

Last I heard it will have carbon fiber body parts and retail for around 75,000.00 no joke! Looks like a 6.4 liter with 3v heads is the latest.

Looking at the CTS-V specs, it makes sense to me.

4.15" bore w/ the same ol' 3.62" stroke crank used in the LS1, LS6, and the LSx trucks. Whaala 6.4L

Using current available parts will reduce costs, and this set-up would be a sweet top-end tach lover.

02 Red Hawk......I'm with you it will be a 6.4L 500/500....at least that is what i have been told by my inside source

I'm assuming that the engine will be called LS7 but that the car will still be called Z06.

Is the 4.15 bore block an all new block is the question at hand? Is it a bored c5R block or an all new more affordable block? This is the most important thing of all.

The part no. for the block in the CTS-Vr specs is not the C5R block, so it may be a special sleeved one, or a pre-production LS7 piece.

Just to add some more fuel to the 427 fire... (click on "Seven litres for HSV GTS" link under LATEST CAR NEWS heading):

wtf is HSV?

AgentOrange

Holden Special Vehicles or something like that. They have some nice rides. Go to www.holden.com.au and under new cars click the HSV link.

Heres is what I have heard, nothing in stone, but what the hell....

When we were in BG for the f-body gathering in Sept., we took the tour of the plant and the only thing we could squeeze out of the tour guide was there was a zo6 in the plant (behind close doors of course) and the engineers were still working on the car as they were still not happy with the final product. He did say it would have 500hp, but he also said the way they were changing stuff, that may not even be correct.

At Road Atlanta, Dave Hill was very tight lipped. (expected) But he did mention they were looking at two weeks to get this thing right and still had alot of work to do.

So, as far as what the car will have, they themselves may not know yet. Its amazing how much testing and work goes into perfecting a Vette.

SEVEN LITRES AND 373kW FOR HSV GTS
CarPoint has learned that the 7.0-litre Gen IV V8, to be unveiled in the Corvette Z06 at the Detroit motor show in January, is almost certain to power the next generation HSV GTS sedan and coupe. The new engine, due for North American launch in the Corvette late in 2005 along with a new six-speed automatic gearbox, could be here in early 2006.

More info on the potential for a 6 speed auto (for the base LS2 cars only I would assume for Dave Hill said the Z06 will never have an auto) as well.

I had read earlier this year that it was going to be a 6.6L which is 400ci. where did the 6.4L come from? But no matter what a 7L would be better as the old saying goes there is no replacement for displacement.

LS1LT1

iTrader: (16)

I have never heard of the 6.6L thing, only 6.2, 6.3 and 6.4...and 7.0 of course.
The 6.4 comes from a chart of new/upcoming GM engines slated for production that leaked out.
Now there's talk of TWO Z06 models, 500hp and 550hp (maybe 6.4L and 7.0L?).

Rumor has it that they were unable to make the target 500hp with the 6.4L setup and so went for the 7.0L. I don't think I'm in the minority hoping for the 427, but I guess we'll have to wait and see...

firefighter

I heard something about having trouble meeting the 500 mark too and thats why the worked so hard to get the weight down below the 3000lbs mark. But I agree that if their hand was forced to go to 7L due to the 500hp mark great for us b/c we arent going to be worried about making some emissions/mileage/C.A.R.B. bullsh**T. b/c lots of people are gettin 500 out of a 5.7 so you know GM could've done it but no matter we're gonna raise all kinds of hell with 7L.
