My cam'd LS1 at idle

Thats why it sounds so good.
....lots of people think cat's help sound for GMMG and some cams. I certainly do not like them at all. Is that supposed to help me? He said that more duration as well is idle speed play a factor. I mentioned that the 224 has more duration in my post. I've heard the 224 with a low idle and it still doesn't sound as tough as that cam. That's why I said there must be more involved than the duration at .050. Both cams have XE lobes as well, if I'm not mistaken.
Mr Casey just needs a new clutch so it won't slip at the track.
In case some were wondering, those wavy lines at the beginning of the runs were caused by the dyno drums not locking up correctly, dyno has been fixed since then. They can unlock the drums so they can dyno bikes.
As an aside - Bill did tune my car and I could not be happier with the tune. I think if I wanted him too he could even tame the idle down to near stock - but I do not know why anyone would do that!
Like Ryan02SS pointed out, you are mistaken, the lobes of the two cams are different.
And to answer your question: Yes.

That is what makes a cam lope. Not the size of the cam.
In addition to that, idle speed and type of exhaust used.
The 222 112 has a -2* overlap
The 224 112 has a 0* overlap
So the 224 112 should lope more

There is more info on overlap in the sticky: https://ls1tech.com/forums/generation-iii-internal-engine/327734-cam-guide.html

The 222 112 has a +2* overlap
The 224 112 has a 0* overlap
So the 222 will lope more

Are my calculations wrong? I've got O* overlap for the 224 112, and -2* overlap for the 222 112. This is why I thought the 224 would lope more.
Overlap = (int DUR + exht DUR)/2 - (2x LSA)
So it is -2
I meant 2* on the negative side LOL
So, cams with positive values have more overlap and therefore lope more.
Now the tempo of the lope will be affected by the type of lobe used and amount of duration used.
Like a XE-R lope of x amount of overlap will sound more nervous than an XE lope of the same x amount of overlap.
Thanks for catching that Redneck.
My post is corrected.

So, cams with negative values have more overlap and therefore lope more.
According to the Cam sticky, as overlap pertains to emissions:
"If you have the sniffer for emissions either go with the cam of your choice and pray you find a good enough tuner and have luck on your side or choose a smog friendly grind. Keep the overlap in check, the more negative overlap @ .050 the easier it will be to pass."
