    Thumbs up 98 Trans-Am -- Heavily Modded Race Car

    Hey guys,

    I never thought I'd be doing this, but I think I'm at a point now that I need to get rid of this car and let someone else enjoy it. I bought the car brand new in '98 and have been the only owner. I know I'm probably missing some stuff, but this is what I remember. There's a lot of things that were done on the car which were custom made, so there was a lot of R&D and "tweaking" if you would to make this car run, as well as a ton of money.

    Here's some information on the car:

    408ci 14:1 solid-roller motor (6.0L block) built by Erik Koenig in Houston
    SCAT Billet 4" Crank
    Heads re-ported by Greg Good in Houston (flowed over 320cfm / 190cfm)

    Coan 6000rpm stall 8" Converter (custom built for this car)

    Spohn Solid Motor Mounts
    HAL 12-way Adjustable Shocks (front/rear)
    Pete-Z Bars
    IRS Torque Arm (this is the one that bolts/welds into the transmission tunnel)
    Hotchkis Rear Control Arms
    (probably missing some stuff here too)

    Other Mods:
    Custom made high-capacity radiator
    Whisper Lid
    K&N Air Filter
    Vaccum Pump (pulls roughly 12" of vaccum)
    Custom made valve cover spacers (oil resistant rubber)

    - Oil Pressure Gauge (mounted in dash)
    - Coolant Temp Gauge (mounted in dash)
    - Fuel Pressure Gauge (mounted in dash)
    - Nitrous gauge (mounted in dash - never used)
    Weld Pro-Star Wheels w/ ET Fronts and ET Drags 28" x 10.5"
    Fikse FM-10 Wheels (17 x 9.5") with Tires (Michelin Pilots in front / Nitto Drags in rear)
    A/C removal
    Heater removal
    Sound deadener removal
    Power Steering removal
    Other miscellaneous weight loss

    Last time I weighed the car, it was about 3100lbs with me in it, but you wouldn't be able to tell unless you investigated under the hood and inside very closely. Also, I'm sure it's slightly heavier with the iron block.

    The suspension has been tried and true on the car, as well as dialing everything in. On my old motor which was an 11.2:1 pump gas 408 with a 260/266 cam, the car was cutting a 1.26 60' all day long. The motor was hurt though with two blown head gaskets we were having to reseal after every pass (it was a track weekend, so we did what we had to do). The car still ran extremely strong though. That motor was scrapped, and what is listed above is what's in there.

    This new motor has never been run or been on a dyno. It starts though and sounds extremely strong. I am going to take it in the next week or so to get tuned. I don't plan on running it at the track though, I will leave that to the next owner.

    Here are some pictures:

    Here's some video:
    - Racing at No Problem Raceway (awesome wheel stand)
    - Major kill against a '69 Camaro with some engine work

    Asking $20,000 OBO - Will consider trades as well. Reply either here, or email me at

    Keep in mind guys, I'm very flexible on the price, I'm just putting a price up there if I have to...
