Nice numbers, get that beast to the track if you can before the weather shuts down the fun for the winter.

Keep us informed and fill us in. Any pics of your GTO?

What about intake (i.e., FAST90)? What supporting mods have been made to the GTO to produce those performance numbers?

Yes, Fast 90/90, Kook's 1 7/8 with cats, stock w.p., stock rockers. Smallish cam and a great tuner.

Is there a FAST intake specifically for the LS2, or does it require some finagling to get work? If the latter is the case, would you mind describing what it takes to get the FAST90 intake to work on an LS2 (i.e., modifications required)? Thanks.

Nope, just a regular FAST 90 ported by me.
