It feels THICK from 1800-4000rpms... Throttle response and tip-in will cut you face off... just brutal...

Mine with a tr224 .563" 114 cam made 423/434rwhp/tq.(Torquey) Nice low end and mid range and peaked at 5500rpm and fell of at 6000rpm. On the 346 it peaked at 6000rpm and fell off at 6400rpm. Then I went to a 230/238 .600" 113 cam. Here are its numbers 448/442rwhp/tq. Lost 1700 rpm of usable torque, motor was lazy (Surged badly). Then I went to a new cam 228/228 .630" 114. All the low end and mid range back and feels as strong as the 230 plus cam up top. Just need a tune. This has stage 1 livernios ls6 heads and a ls6 intake with 80mm TB at 10.8:1 comp. Was told to go to the fast 90mm intake and throttle body system to pick up power.

Yupper... I know I am intake limited at the moment... I did not use a FAST specifically because the amount of valve-train noise that comes through it. It is obviously thinner than the LS6 intake... I am "hoping" the new Weiand Street Warrior intake plus a LS2 90mm TB will pick a little more HP... heck it has to be better than the stock intake and 78mm TB...

I didnt notice any difference now that I think back..
Why not just cover the FAST with some kind of sound deadening material?

By buddy just did 472/430 with his 383, 5.3 heads with a 232/234 cam 10.8 scr.
And of course with all supporting mods including a Fast 92/90.
My Fast increased my valvetrain noise also

I'm getting ready to put a Texas Speed 383 bottom end in my z28 m6. I have all the bolt-ons including fast 90 setup, what could this setup make with stock 2000 heads with valvetrain and my ms4 cam?
