Specific power doesn't count, total power does, and GM is keeping the p00prod dream alive by keeping pace with other V8s in their respective classes.

Give the L98 the compression ratio, heads and ECU/FI system, and yeah, you'll have about LS3 power/torque curve; IOW, cam lift/duration by itself doesn't mean a whole lot.

Sporty's comment was about specific output.  My original response to his comment was on the topic of specific output.  Welcome to the conversation at hand.  The relevance of specific output is a separate topic.

Cam profile is one of several major contributors to power curve characteristics.  If you're going to make a comparison about the affects of different cam profiles, as you tried to do with the LS3 and L98, you should select motors that are essentially the same except for the cam profile.

Specific output = total output when displacement is constant, as it was between the LS3 and LT1, right? There's plenty of room for increases in output; specific or otherwise; in the Chevy V8 with its current configuration (i.e., pushrod, 2-valves). Chevy has been doing so for decades and though in theory improvements can't be infinite Chevy has a long way to go before hitting maximum.

You addressed cam profile in a vacuum, and so did I. Generally, more lift and duration increases powerband RPM but that doesn't necessarily mean that low end power is sacrificed, if the engine makes a whole lot more power (as is the case of the L98 vs. LS3 - the former has lower peak power/torque RPM but the the LS3 is going to have equal or more power throughout the lower RPMs, and obviously hugely more at higher RPMs).

When did pooprod stop being the forum Easter egg?

BTW, autocorrect wants to turn pooprod into "polo prod."

The biggest thing I dislike about the stingray is the lack of a fixed roof option. Oddly, it's a big deal to me. Even weirder if that was one of the "big" reasons to buy a z06.

You should see the debate about this on the Vette forums...

I don't know what the debate is, but to me it's pretty cut and dried. A fixed roof is going to be stiffer. I'm buying a race car, not something to drive to the bar and take the focus off my receding hairline and erectile dysfunction.

The Z06 guys say the same thing. But the base/GS guys like the option of having an open roof.

To be fair I've never seen the point of a targa 911 either. A car should be fixed roof(sunroof option) with a convertible option. A removable roof section(or t tops) just takes a perfectly good rigid roof and turns it into a noodle. While offering NONE of the open motoring experience of a convertible.

Convertible 911s are so ugly, though. :P

I don't think the 991 convertible looks bad.

I would imagine the removable roof vette is still more rigid than the vert.  It also has quite a bit more cargo space than the vert.

It's the best looking of all the 911 convertibles, but it still looks like a bumble bee's ass.

Woah  Where did you get those stats?  Just curious, I haven't been following it these last few days.  I'd be shocked if this thing actually comes out with auto-only.  DSG I could see, but not a conventional torque converter auto.

This reads as if the C7 Z06 will have a removable roof. I really really hope that isn't the case, GM should know better.

Is that a black hood or does it have the cheeseball window like the c6 zr1?
