I read somewhere that the LS7 will use the C5R block. Of course it will have to be modified a little for the external knock sensors and such. The C5R block is expensive because it is not mass produced. It has about the same amount of aluminum as the LS1 lol. It would not take much to have them mass produced IMO. I tend to believe the rumor I read because it would seem to be cost effective for GM. The question is what size crank and rods will be used. Everything I've heard is it will be a 427.

I think those expecting or counting on GM using a 7 liter 427 motor for the 2006 Z06 will be greatly disappointed. MY $ is on a 6.4 liter motor (at the most) making 500 ponies (if were lucky) in a 3000 lb car!

I am going to say this ONE time at the end of the thread:

- 6.4 ltr engine
- 475 HP first year, 500 subsequent
- The Z06 namesake remains, there will be no mass produced "Z07"
- Body modifications will be both functional and aesthetic
- No magnetic ride selection, all major suspension/brake components will be upgraded
- $9,000 over Base C6 manual

we all have to give GM its props for sticking with the the traditional pushrod v8's and making their power the old fashioned way, albeit there is nothing old fashioned about the LS1

ford couldnt do it even with the 351 they put in the original lightning ... now they have gone to supercharging 4 valve headed motors only to come up shy of the LS6 2 valver

now GM will be making 500 hp with the LS7? all of a sudden the Viper doesnt sound to tough after all with its V10 .... You really need to stop and think whats going on in front of our very eyes ... the muscle car era that peaked in 1970 that we hear so much about, the hp wars, that will never be the same again? They were nothing to what is going on now. 400 - 500HP, 25+mpg, smooth running small blocks? Wow

I was at Road America Friday and Saturday for the World Challenge/ALMS races. While there, I stopped by the Caddy team transport where they had three entries for the World Challenge GT race. A team manager said that the Cadillac CTS Super-V, if produced, will use the 427 engine. 600 hp for a supposed $65k. In my opinion, it would be sick for Corvette to be trumped by a Caddy.

Full-Force, ill give some props to GM, when they start making forged bottomends (like the new cobra has) for our cars. Everyone here would love to have a stock car that could handle a 300 NOS shot, or 20psi of boost on a supercharger.

My local dealer told me there isn't such thing as a C6 Corvette. Don't believe anything a dealer says.

It's 100% sure that it will be called a z06, not a z07. Also I will say this, believe it or not, it will be a 6.4L producing just under 500hp.

I work at a ford dealer. If you want to find something out don't ask sales dept. Everysales men here is a moron. And they don't care about the ones they can't sell yet. Most of the time only the guys in service can tell you something.

Its seems that everyone is firm with the 6.4 liter idea.

I think most would agree that GM will not order/build/manufacture a different crankshaft for use with the new LS2 block to make the 6.4 liter mark. It would not be as cost effective.

It would seem to me the most cost effect way to achieve 6.4L would be to continue using the 3.622" crank, rods, pistons, basically the whole damn rotating assembly with a larger bore cylinder block (4.125"). Especially if they plan to build the car in mass quantities. I doubt GM would use any kind of forged components in the rotating assembly.

Like I said before I'm crossing my fingers for a mass produced 4.125" bore aluminum block that would probably be a third of the price of the C5R.

It does not seem too likely that they'll use the same pistons if they go with your hypothesized bore enlargement. Also, emissions will leap into the stratosphere with that large of a bore. So, that said, increased emissions and eight new pistons with rings vs. a new die set for a (relatively) limited run of longer strokes and pistons with adjusted pin height (possibly already available in another engine configuration (?))... Hard to say which way they'll go, but the current engineering trend seems to indicate that smaller bores are preferable for emissions and economy.

Hmmmm....

A 103.8mm bore comes out to 4.087".

Unless my calculations are incorrect, 4.125" bore = 104.78mm.

Perhaps that was a typo and you meant 104.8???

103.8mm would put them short of 6.3L with a 3.622" crankshaft.

Would you if you weren't an enthusiast? I sold for 3 years... But I knew more about the HI-PO projects than most of the techs did. Why? Because I care.
