Discussion
Having read allot and spoken to a few people I'm thinking of prodding my engine with one of these sticks, any thoughts or recommendations from those in the know..... 
Lingenfelter GT11
215/231
.631/.644
118
Obviously I will be doing springs, timing chain upgrade etc to support and limiting my boost level to 9psi so the exhaust valves don't drop off and as with any performance cam the springs will become a service item.

The thing is, with a bit of boost there are literally hundreds of cams that will work great. So it would actually be hard to pick a bad one ( assuming a little common sense )
More might depend on emissions, idle, rpm range than just plain boost used.
But any of the above mentioned would work fine, along with many others. And it'll be hard to get a definitive answer as to what is best, even more as as all they ever say is "custom grind", "custom grind"
Even though many custom grinds will be the same as shelf grinds....simply because there are so many shelf grinds in the first place.

Have a word with mineme68 http://www.pistonheads.com/gassing/topic.asp?h=0&a...
Ignoring the numbers for a second, this tells you what to expect from the GT9 in your LS3 - an engine that likes to rev, doesn't spin the wheels unnecessarily and makes power all the way to 7k rpm.
By Comparison you could have this! My last cam:
OK, it was in a stroked motor but the point is still the same - made loads of torque at low rpm and broke traction easily. Great for towing a caravan but little else.
The idle of the GT9 is really smooth but it shifts some gas which makes for a really nice exhaust note, especially if you forget the cats.
