Its an advance ground in which will bring torque in sooner. It also affects the intake centerline (ICL). For instance the cam is on a 115LSA +3* advance ground in so the ICL is 112. Advance also affects PTV. The more advance the closer PTV on the intake side but adds more room on the exhaust side.
interesting
Its alot more detailed than that, thats just a quick off the top of my head summary. I dont know alot about them, but from what I have been reading that seems like what it means.

ls3 heads are extremely impressive for an OEM head...

its not a specific boost cam... but i was told that its boost friendly
I'm almost certain mine is a 112+2 ... i forgot to check last night, but i'm nearly certain ... my cam is 232/240 .650/.650 112+2
i love the sound - the power is great, and has a VERY broad power range... Power comes in pretty early for a cam that makes peak power at the 6600 rpm cutoff... not sure at what RPM it would max out, but i see no need to find out.. :) ...
i'll have to find the dyno sheet and post it for Cam's reference

- bolt-ons, tune, lots of carbon fiber (642/671 rwhp/tq)
D rod has a similar cam he has a pretty choppy idle but it seems to wind up fast I have no experience with the + degrees it's a pretty cool concept though building advance into the cam
here's the dyno graph for my 'Vette

From what I've read, and dyno sheets I've seen on Camaro5 it doesn't seem the FAST intake improves the horsepower very much on the ls3's. At least not worth the $ in my opinion, LOL. Not seen much improvement in head porting on the ls3's either, so after the cam I'm not sure where else to go with the car powerwise. Was thinking gears but seems they are very unreliable in the camaro once you go above 3.73's, and I'd want 3.90 or 4.10's
Have 4:10's in my vette love them how are they unreliable?
Heads the porting needs a huge cam to show benefits. Shaving them for a bit more compression and a good valve job will add some pep though. But we are only talking 25 ish hp
there are lots of threads on camaro5 about gears crapping out very quickly in the 5th gens, especially richmond gears. even a couple shops i talked to wern't very confident about how long they will last. not sure if it's a camaro thing or what. i'm just going on what i'm seeing on the internet though because i'm not that familiar with this newer gm stuff.
