Choosing a better cam than a Elgin Sloppy stage 2

Choosing a better cam than a Elgin Sloppy stage 2 I'm on the hunt for a something different than a lot of people are doing. I know I can get an easy 500 crank HP, but maybe I can get more and still be 99% streetable. Engine hasn't been built yet, so changes can be made.
Engine- L96, truck, Higher compression LQ9 pistons 10.1 comp, Gen 4 Heads stock 823 with Pac 1218 or 1219, trans 4l60E, 3.55 rear, car 3000lbs
E-1840-P .585/.585, 283/286, 228/230, 112

E-1840-P .585/.585, 283/286, 228/230, 112

Stay with your same 228/230 - bump lift to .653/.638, get compression up.

Holdener's cam shootout "SS2 vs the world" showed the SS2 improved both bottom end and upper power gains on a 6L N/A engine, (which is hard to do), beating most "streetable" cams tested. Ran the SS2 in a previous LQ9 build and was happy with the cam choice.

Why would his tests be "skewed"? I'd be interested seeing your dyno comparison tests on different camshaft profiles. Not many people have the equipment or resources to do that kind of testing.

It's usually best to ignore people that show up just to cast shade without offering anything constructive. Nobody actually cares about your opinion when you're not trying to be helpful.
As for the task at hand... I would change heads before I changed the cam, because I just cannot stand LS3 heads on 4.00" bores. But that is not what you asked for help with. Darth is probably right in that cam isn't bad, but could use more lift.
I didn't really know people were trusting stock rockers north of .625" lift, but I believe Darth speaks from experience, and would run what he says with minimal worry.

What the valve reliefs are actually for is to allow you to run more duration and overlap and/or tighter LSA. A flat top piston, somewhere around 10 degrees overlap, you can start to have PTV issues, depending on other variables.
To put it more simply, a 228/236-108+4 with .525 lift is going to have issues and require flycutting. a 228/238-112+2 with .700 lift will clear just fine.

Certainly welcome to your opinion as you probably dont get your hands dirty on cars everyday and neither does he. He's a technical writer not a mechanic or racer, just because he humps a sponsors engine dyno and waves his hands around for youtube clicks doesn't mean he's always correct.

Is he always correct? No, and he says so quite often.
So before you get your panties in a knot and start getting diarrhea of the keyboard, check your facts, and maybe YOU will actually know what you are talking about, but I doubt it...

The tests he puts on his YouTube channel, except for ones he did many years ago, are not sponsored. He will mention if a part is donated, but then that part is usually not the focus of he test. He usually tests to find differences between different configurations or effects of different spec parts, not to compare between competing manufacturers. Usually if he is comparing cams, they will be different spec ones from the same mfr. like BTR or Comp. to show the effects of different durations or LSA's for example
He gets his hands quite dirty, as his early writing is the outcome of HIS wrench turning. He knows his way around the toolbox. He was a mechanic/racer BEFORE he was a writer. The only dyno he uses unless out of state is Westech's, who have no parts to hawk. They are strictly a testing/tuning facility who he uses for his testing. They are a neutral party here.
Is he always correct? No, and he says so quite often.

He went to YouTube when magazines quit printing to gain what turned out to be a great outlet of good info. Nobody else is doing it in the depth and detail that he does.
And whatever he does, gets shared with whoever cares to watch, which is way more than you could ever do. Very few can test for themselves what he does. If you don't care to believe him, it's your loss, but apparently you're a legend in your own mind, so there is that. LOL
