The dyno test we've done on the 102 mm showed only a 6 hp gain on a built 427 LS and the gain was way up top in the rpm range. If you had no manifold or you were replacing a truck manifold for a car manifold then it's probably worth the investment but if you already have a manifold it probably isn't. The LS6 manifold is pretty hard to beat for cathedral port heads.

Basically, the FAST intakes are for max effort people or people who need an intake. The dollar per HP is not there. There are other bang for the buck ways to increase power on the LS.
Have you done headers? Cam? Pulley? Heads?

I think the fast 92 uses the ls1 style injectors if that matters for you unlike the newer 102mm intakes. The best fast is the truck lsxrt if you can fit it.
