Your thoughts..90/90 or ls6 on the 408

As of now I have a ls6 intake, H/C with a stock ported TB. I have done some searching but didnt find what i was looking for..Do You think it would be worth the money to go with the fast intake and 90mm Tb over my ls6? Does any have a dyno of a before and after on their storker? I have also heard that the ls2 does not flow as well as the ls6, but what about on bigger cubes? i would go with the ls2 and Tb cause of the price, but dont want to risk anything with out some input.
Thanks,
Managment

No question about it the 90/90 is very worth it with your setup.
A typical 20+ HP is gained from the LS6 intake/ported TB to the fast 90/90 on aggressive H/C combo's or bigger cubic inch combo's.

The fast intake looks promising. What about the ls2 with the 90mm with the bigger cubes? Any gain there?

Good info to know. These ls2 intakes must be holding the C6's back by a good amount. guess it is time for a 90/90!

Ditto, ported 90mm FAST is worth possibly 30 rwhp over the LS6 intake. I gained 28 rwhp on my 346.
