Fast intake vs ls6
Bunch of info in there.
That could get you pointed in the right direction until someone can chime in
Based on my flow testing in the thread mentioned above, the 90/92 cat will move ~15 cfm more of air a peak lifts. That's potentially 10 to 30 hp generally speaking depending on cam, rpm and other factors in most applications.
Best bet for long term is to sell the LS6 and upgrade to a 90/92 Fast as it would have more potential after porting in other bigger engines etc.
Just my humble.02

I may give up a little down low, but it's got a 4400 rpm converter and revs. Plus I can grow under the intake.
