This is mine, vvt ss1, L99 with LSA Supercharger... Great idle...

This is my opinion and its all relative. I personally can DD a nonoverdrive car with a full spool but I know there are guys out there perfectly satisfied with a LS9 cam.
Torque starts to take a good drop below 3500rpm when you go over 228 or so intake duration. Yes overlap plays a part too but Im more speaking on low end torque.

My cam spec is 226/236. I pick it up Wednesday and it sounds like im right on the edge of drivability, guess I will find out then

If its cut tight like the ASA yes but like I said its all relative.

My current blower cam is a 227/235, .641"/.649", 114 LSA from TSP on the 416, which is a larger motor but lower compression. The cam I had in the stock motor was 225/230 .629"/615", 114 LSA with stock compression ratio. It was easy to tune, as it had a slight negative overlap @ .050" lift. The new one has 3 degrees positive overlap, just like the one you are asking about, and was pretty easy to tune also. For me, right around that area of overlap is the compromise area for a DD. I've tuned cars with 15 degrees or more overlap, that is definitely not DD territory. I never recommend a cam with more that 5 degrees of overlap for anyone who primarily DDs their car, unless they specifically say they don't care about the harshness.

That's awesome! How is the drivability?

With the first cam, I could drive at 45 mph in 6th gear with no surge at all. The cam you described would have 2-1/2 degrees more overlap, so you may start to see just a touch of surge at high gear/low rpm, but I doubt it. But I definitely can recommend the 225/230 cam from TSP, which is why I ordered the second cam from them as well. Not sure what lobes are being used on the cam you originally asked about, but the TSP cam is really well-mannered and I didn't see much increase in valve train noise.
This is only my opinion, but I would do the 225/230 cam before I did the 227/235 on a N/A build, even though I used it as a blower cam. I know many people would recommend more exhaust duration, but increasing exhaust duration either means you would have more overlap, or would have to run a smaller intake lobe, assuming the LSA stays at 114. The 225/230 is actually the smallest LS3 specific cam TSP makes, because it behaves nearly stock, due to the 1/2* negative overlap.

I have a 232/240 .626/.626 112LSA and it drives pretty damn good I daily drive it. No complaints on drivability really

Very similar to mine and if you are getting who I think you are to tune it, you are gonna love driving it. I do mine, even in Atl.

There is a lot of good advice here, but if it's your first cam, maybe choose a little more modest path, and cams are not permanent either. You can always put a different one in later at your next spring maintenance point and would likely not cost as much. The permanent excitement factor will offset any drivability concerns. Frankly, after driving this first cammed car of mine, I feel I could handle bigger without any issue and you probably could handle that one. See if someone near you has a cammed car to test.

For some DD M6 drivers, this may be quite significant.

Ultimately, a DD type, particularly urban, must ask themselves right into the mirror,

"do I risk getting sick and tired of my extroverted cam, and wanting to go smaller after a couple of years, or do I wish it had been more extroverted to begin with?"

Naaaahh..It's gonna drive just fine.
