Anyone install a LS6 intake manifold onto their 5.3?

Seen some LS6 manifolds on ebay from higher performance vehicles. I looked into the FAST LSX intakes but damn are they expensive for the amount of power you could possibly get, and not to mention having problems finding T-bodies that are large enough to fit them without using the reducer. So is it worth the $140 ish dollars in the intake swap? I guess I would also need to find a bigger T-Body since the stock on mine is I believe 78mm?

Disregard, found some good info and man is it a hellova project to do. Expensive too since its the ls6. Ls2 swap is suppose to be a bit simpler but not as much gain as with the ls6, and the ls6 won't lose much if at all bottom end. Really this swap would be for a more high performing engine that reved way into the 6k plus. Though our trucks are capable, our intake manifolds are actually for more low end power so power and torque taper away quick after 3900 I think.... but the ls6 will actually keep power moving up rather than die off when reached into the higher rpms

But i really have no use so I'll stick to stock for now.
