The L76/LS3 intake and the Fast LSXR 102mm intake will fit under the stock cowl and appear like factory

You can also run a Single plane intake with a Elbow made to clear the stock cowl but there have been reports of the elbow robbing power. GMHTP just did a article on a 408 with L92's and the elbow made more power PEAK but loss a TON down low and in the mid range.

Sheet metal intakes can be made to fit under the cowl but from what I was told it would be more for track use then street use.

Default Ls3 manifold on L92

SLP engineering is doing supercharger installs on the new camaros and selling the new take offs with injectors and fuel rails on e-bay for 299.00 + shipping and handeling . Hard to beat that deal

L76 and LS3 manifolds are slightly different

L76 has a press-in MAP hole and accepts the LS2 MAP sensor but the LS3 has a bolt-down MAP design and does not accept the stock LS2 MAP without some convincing

I run an LS3 manifold and all i did was buy another MAP sensor gasket and 'double up' on my LS2 MAP... crammed it in there and its been fine for over 3000 miles. others have done this with success as well.
