    never never never go with a fast 78 combo..its a waste of money and time..if going fast...go 90/90 or else just stick with the ls6

    they discontinued the FAST90 and introduced the FAST92 as its predicessor...

    i agree w/Shady, go FAST90 or FAST92, never a FAST78. In my personal experience I found the Ls6 intake to be a joke on my H/C setup. I swapped to a self ported FAST90 and gained 35rwhp over the Ls6 i had on my car...

    its really not worth stepping up to a FAST90 or 92 unless you have H/C done. thats where the difference will really be noticed...

    it all depends on mods, but if you look around people are selling the 90 somewhat cheap because there upgrading, just an idea
