I love my 4.10s (non-Z51 trans) and after 40k+ miles with them, I never get tired of driving the car.

Your thoughts on 4.10s
'05 C6 non Z51 w/G6X3 cam, LS6 ported heads, Lingenfelter ported LS2 Intake, ported TB, Vararam CAI, LG PRO LTs and Xpipe, B&B catback, tune. The car made 460rwhp 408rwtq and has ran 11.7 @ 125.7mph on the stock clutch. Adding a LS7 clutch/flywheel, FAST 92 and 4.10s, what do you think it should run?? and how much power would it pick up on the dyno with the new mods?

You probably wouldn't see much on the dyno at all. The clutch won't get you power, the FAST will give you more in the midrange, but probably only 15-20 RWHP at peak, and the 4.10s though increasing acceleration rate, usually show about a 10 RWHP loss on the dyno compared to the stock 3.42s...so your numbers may inly increase slightly.
BUT....those mods will make the car feel like a new animal....the low and midrange punch will feel like you lost 500lbs from the weight of the car....the FAST and the 4.10s do amazing things, especially with the non Z51 tranny. Just do it, you wont regret it.

Call me....I'm sure we can help you.
Hey man... The 4.10 should have come stock in the C6! Ask any 4.10 owner and they'll tell you the same.

Honest Opinions?
They arent for everyone. If you want to run the 1/4 then yes they are great - but you can do thatwith any ratio. With a HiHP Car you will be shifting constantly,every second, no matter what. I had my fun, got it out of my system, and ended up with 3.73's - I absolutely love them.

Anyway 3.90's will get you what you want.
The LS7 is an awesome clutch but just be warned not many people other than Ranger will say its cut out for the track.
The last point is you will only see such an ET if the tire is a MT ET street and you have a decent 60'. The LS7 isnt going to make that easy.

I've posted hundreds of times (one example) that the LS7 clutch has an ugly personality. It's the worst clutch for the track that GM has ever put in a Corvette I've driven. It's ill-suited for a 420 RWTQ car, much less one with even more power.
The LS7 clutch has a propensity to glaze and won't accept a launch rpm above 3600-3700 without compromising the 60' and/or the 330'.
It also produces prodigious clutch dust of elemental iron and copper that attacks the seals in the hydraulics leading to pedal issues unless the fluid is kept clean.
I've managed to adapt my driving to the limitations of the LS7 clutch through experimentation. That led to fast times at the track, in spite of the clutch's foul personality. Were I not a stock guy, I'd go with a better clutch and run much faster times.

SpinMonster, not sure where you got that idea. Wasn't from anything I've actually written. On the contrary....

I have an LS7 clutch in my car with well over 700rwhp and have never changed the clutch fluid. It was already over 500 when I installed it with a fidanza flywheel. My pedal never sticks to the floor which I believe is only due to heat issues weakening the springs in the pressure plate. Since I never launch hard, it never super heats. Those who have had the pedal stick to the floor note its only for a few seconds and then the pedal works right again....with the same clutch fluid. If the clutch fluid was the culprit it would not fix itself until the fluid is changed. My current fluid is about 3 years old.
I guess all this means I too have adapted the driving style to the clutch limitations. I agree 100% with the launch rpm limitations.
