I doubt it would be enough to out weigh the cost of changing everything. I doubt you'll see 10-20 HP difference.

.....And the gain you would see wouldn't be until the upper rpm's. Possibly 6k and above.

6200 rpm actually. The SP has shown no gains over LTx in the idle to 6200 rpm range. Even then, the gains aren't big until 7000+.

The LSX intake manifold design is completly different than ours so that comparison really doesn't mean anything on our cars.
