TPiS ZL9 Cam
Why isn't anyone running this cam??? You might think it would be the best cam of many worlds, specifications 209/223/110, -4* overlap which is the same as a Comp 224/224/114 (Read: Emissions Legal).
On their website TPiS claims no loss of drivability with revs through 6800.
What's the deal?

It might rev to 6800, but would be past it's peak hp at that point. It wouldn't be a bad street cam, but would be considered small. Most are going medium to large with cam swaps.
Since you are looking at odd ball cams, one I installed is 215/231 .631 .644 118 which has -12 degrees overlap, and behaves more stock than the stock cam.

I realize something along the lines of an XER 232 would be bigger though not emissions legal. The advantage here is ability to generate the torque down low yet not run out of breath over 6000. No one runs Grand Am specifications on track or street using this cam?

Since you're in NC I wouldn't think you'd have to worry about emissions since they just do an OBD scan, and if it's tuned to not throw codes you should pass with just about anything, as it is here in WA. California would be a different story, however.

I'm not worried about sniffer at all, I can smog my car in a county vi P.O. box when I'm back in Cali, not even relevant. I'm wondering why anyone is not running this cam in their setup the way it is, torque down low with ability to rev.

You may want to run numbers for powerband for the equation and most likely should, even then this cam has greater capabilities than lots yet at the same time no loss of drivability.

With valve events lined up like this, it's not surprising this cam carries over 6500, however for this to work as the advantage, it needs to generate the torque in the midrange to be good.

are you trying to sell this cam or something?
Most people wouldn't run a cam like this because the gains over stock wouldn't be big enough to go through all the trouble and expense of a cam swap is my guess.
Edit: You know you can also edit your posts. You don't need to make 5 in a row.

These are three recommended for Road Racing:
GMPP ASA cam - 226/236 0.525"/0.525" 110 LSA (medium, 11* overlap)
One of Comp Cams Recommendations - 224/228 .566"/.568" 112 +2 (mild, 2* overlap)
One of Crane Cams Recommendations - 222/224 .585"/.585" 110 +3 (mild, 3* overlap)
Now here's the problem, none of these have torque lower in the powerband, even with gears it'll be tough to generate horses lower in the rev range.
