I'm getting a Fast 90 intake from a friend of mine and just wondering if there will be any power gains from my LS6 intake. I'd like to know all the positives and negatives. I'll be adding a PatrickG cam in a few months, just want to make sure I won't loose anything until then. I made 353 rwhp and 363 rwtq before I added my asp pulley.

Jeff Creech did that same swap for me some time ago. Dyno read 321 with the LS6 intake after he fiddled with the tuning some. 333 after with no extra tuning. Peak for peak was decent I thought considering the stock motor did not require the extra airflow afforded by the FAST intake. What surprised me what that the FAST 90/90 picked up power (though not much at low RPM's ) everywhere. This was a Mamo ported FAST 90 intake and Nick Williams 90mm throttle body.

Make sure you get the intake ported. That way when you finally do the cam and eventually heads she'll be ready. Good luck
