Anyone know what the "sweet spot" rpm range is for the LS3?

I'm going with 4.10. 4.10 gears should be fine, given how super-long (that's what she said) 6th gear is. Hell, I think even 4.33 might workable. My primary concern is more about gear whine than highway fuel economy.

4:10's all the way! Its a heavy car, got to get it moving!! 4:10's in my 95 was awesome! I still got over 20mpg on the highway.

because of the rear tire size, putting 4.10's on the 5th gen will feel like the equivalent of installing 3.73's in the 95 (and, actually, considering how much higher the LS3 revs vs. the LT1, it's worse than 3.73's in relative performance gain).

I have 3.73's in my 4th gen and I get some whine right at 65mph. It's a little annoying, but my exhaust loud enough that it doesn't matter much. |

Not really. How often would you need to be in 6th gear with the stock gear ratio? Almost never!

The calculator that the OP used has a conversion factor of .965 for the tire height. Meaning whatever the tire height is calculated out to be, it multiplies that times .965, which makes the height used in the calculations shorter. It does this to account for various factors such as the weight of the car deforming the tire slightly, which makes the actual height shorter. This calculator will probably provide you a more accurate answer than others that do not use this conversion factor. Notice this one says your top speed in 3rd is 110.1 mph. Also notice how every single test so far has put the trap speed in the 1/4 at 110-111. I've never seen so many tests on one car with such close numbers. I'm assuming that's because at about 111, the rev limiter kicks in, and the testers are running it straight to the limiter to avoid shifting into 4th, which would make the 1/4 times slower. So yeah, raisng the rev limiter to about 6900 would probably net you some faster times/higher trap speeds.

Guys/gals, where are you going to get 4.10s for the factory rear?

Ok, that's what I thought you'd say.
I am 99.9% sure that the Camaro rear is the same as the G8 rear. If that is so, there is NO aftermarket ring and pinion out there. Not in the US and not in Aus. Your choices are 2.92, 3.27, 3.45, 3.70 and that's it. For now.
