Gene @ GM Parts House and Parts Taxi sell a LS7 clutch/flywheel kit if you will that bolts right in to the car w/o problems. As far as how much power it will hold I have no idea and would also be interested. 
I plan on going this route once my clutch decides to go (70.5k on the clock).

I have researched this topic to death. I've posted a few threads, and searched at LS1tech.com
Yes, the ls7clutch/ls2flywheel will bolt up. I have heard that the setup is much heavier than the ls6, and will cost you hp.

Ran the ls7 clutch in my GTO...you'll need an ls2 flywheel and yes the extra weight of the clutch will rob some HP on a dyno...Held up nicely considering the extra weight not to mention the full bolt-ons + medium cam and ported fast 90 that i had on the car. 4000rpm launches and it never skipped a beat! If your not overly concerned about dyno numbers it makes a great stock replacement that will handle the occasional visit to the local drag strip if need be. As far as what its rated to, consider that it does well in the stock C6 Z06 which is a bit heavier and has 100more HP than we do.

I see what you mean. Just had some time to search some threads and it doesn’t seem like that good of deal when keeping performance in mind.

I have decided to just suck it up, put the spec 3 in my car, and add the ECS brace and output shaft.

I don’t plan on doing much drag racing if any (no 1/4 track within 2.5hrs) and although I would like a bigger cam it most likely won’t end up happening. Mostly my car is for weekend fun, autox, and 3-4 track days a year. I found a OEM LS6 replacement clutch kit for $423 on a site and I was looking at the Exedy stock replacement or a Spec Stage 1.

As far as going with a spec I would go a bit further up the line than just a stage 1. I have a 2+ and it feels like stock with the exception of a slightly heavier pedal. It all boils down to how much $$ you want to spend.
Not too long ago a vendor was trying to help out a customer and was selling a new in box Spec super twin for $900
and I didn't see anyone jump all over it.....now that would be a great buy.
, but fun, fun, fun
