Ls7 intake swap

Would an ls7 intake work on and ls4 following the sticky on intake swaps?

The LS4 needs a cathedral port intake (LS1, LS2, LS4, LS6 or the aftermarket equivalent).

I know the fast doesn't work but what about these bbk intake or the metal ones I see on eBay?

The fast can also be made to work (as long as it is a cathedral port version):

Almost any cathedral port intake can be "made to work" as long as they are not tall truck intakes (unless you want to cut your hood).

The FAST definitely does work. I'm running the 92 and it was an easier swap than the LS6 I believe. The 102 requires quite a bit of chopping up to the manifold and I don't think anyone's making enough power to really benefit from it. Hell I'm not even maxing out the 92. But if you want an LS6 manifold that's ready to be swapped on I'm selling my old one.
