I was also wondering this. From what I've seen the truck intakes are far superior to the stock ls1 intakes and show some advantages to the ls6 as well. They pick up considerable low end torque and don't show any hp drop offs until the upper rpm range, somewhere at or above 6000 rpm. The only real problems with them is fitting them under the cowl; does anyone know if shaving is enough to squeeze them under? Also it was shown that when used with larger more aggressive cams their advantages slowly disappeared.

From what I know the tbss intake is a much better option over the regular 5.3/6.0 intake. While they are less common and more expensive, in stock form alone they totally outperform the regular style truck manifold. They come stock with a 90mm throttle body that can be heavily ported. Also the intake itself can be heavily internally ported, some outside companies are offering it, but it costs quite a bit. By this point though, unless you are finding things cheaply an doing everything yourself, it's most likely more cost effective to buy a fast 90 or other competitive intake. On top I that you don't need to hack your cowl.

A little digging found a nice comparison shot. Stock, non-shaved, truck manifold on the left and what I believe to be a ls1 on the right. Sadly it appears that even with extensive modification some cowl would need to be chopped.
If you could somehow get it in there though, it would look pretty clean. Here's another one done then sprayed with some gloss krylon. It would really pop out if put into a 4th gen engine bay.

Most likely, but with that comes multiple other problems. Lowering your engine in turn lowers your trans, this causing shifter and mount problems. It would also cause multiple problems inside your engine bay as well as move exhaust much lower to the ground, which is bad news for those with lts. This could also throw off distance/geometry between trans, driveshaft, and rear, which may or may not be an issue.

I believe what would most benefit from this would be anything that would be mostly daily driven. The gain of low end torque would far exceed the loss in upper rpm hp. It may be able to increase mileage and would most likely give a bit more throttle response and bite off the line.

I see this as more of a, because I can and want to be different, sort of thing. Just like I want to put a 8.1 496 tall deck in a 4th gen. While it may be easier, cheaper, and more successful to build a 6.0 I just think it would be sweet to say I have 500 ci big block and you don't. Fitting a shaved truck intake is the same thing, it's never, if seldom, been done and is something interesting to see in a engine bay.
HAHA! You and I think alike!
I was thinking of doing one of the Avalanche BIG BLOCKs, but there's no aftermarket and I was told that they are weak.

The runners in the truck intakes are shorter than the LS1/6 runners. The truck intakes also have more plenum volume to supply the motor. And they have no issue going past 5k rpm. The only downsides are they are big and ugly.

Sorry for going off topic so here are some more pictures of a modified intake. There is one on a motor for reference to actual height, these things are gigantic. It seems if you go low enough into the ***** they turn into holes, which is why this one had an aluminum top cover put on.
