Next Corvette to Get All-New Small-Block
I think we all knew this...I wonder if the 5.5 liter is accurate? 440 hp is only 4 more than the current C6, I imagine weight savings will be significant.

C7 will Debut with GM's latest V-8
From the August, 2010 issue of Motor Trend
/ By Mike Connor
According to sources inside GM, the C7 Corvette will be one of the first cars fitted with the next-generation small-block V-8 GM has announced it is investing $890 million to develop and manufacture.
GM has confirmed the new small-block V-8s will feature aluminum blocks and heads, direct injection, and a new combustion system. Our sources say the C7 engine will displace 5.5 liters, with a target output of about 440 horsepower.
The new small-block will retain a traditional overhead-valve layout, ensuring compact dimensions and lower manufacturing costs. Prototype engines reportedly are already running on test beds in Detroit.

The Gen V V8 is no secret but the details about it are not clear. DI, cam in block are the rumors. The displacement is interesting because 5.5L is what the ALMS C6R's are racing because of the regulations right now. And that's where the Gen V is supposed to make its debut even before the C7. IIRC

I hope the 5.5L rumors are true. I know a lot of people here say it will be 5.3L. 440hp (or any number slightly higher than the current LS3) and a drop in weight to say 3000lbs. would be perfect for the base car.
6.2L and 505HP+ for the Z06?

The Gen 1 smallblock ran from the 3rd year of the C1 all the way into the C4 years.
The Gen 2 smallblock debuted in 1992 which was 8 years into the C4 run with 5 years to go.
The Gen 3 smallblock debuted in 1997 which was the first year of the C5.
The Gen 4 smallblock debuted in 2008, which was the 4th year of the C6.

I wouldn't consider it a given by any stretch. It's only happened for 1 out of 6 generations of Corvettes.

That is correct. The last time there was a Corvette Generation change that DIDN'T get an engine makeover was the Gen 3-Gen 4 update about 30 years ago. No reason why Chevy would stop now.

Where are you guys getting the bit about weight savings? The article doesn't mention it. Did I miss a previous thread?
Sometimes I worry about the implications of the horsepower war. Too many high-performance engines these days don't offer enough low-end torque to be exciting when driven at legal speeds. A decrease in displacement and an increase in peak horsepower usually means a decrease in low-end torque. I'm hoping that the inclusion of direct injection with these changes will counteract that difference.
