    Default What numbers are you guys producing

    What numbers are you guys producing with Gm847 and ported heads. Also what kind of track times do you guys get out of it.
    I currently have
    Gm847
    Ported heads larger valves and matched intake,
    52mm stock ported to
    355 forged bottom end
    4l80e
    Dana 60
    Supporting moda
    I understand with the 4l80e my numbers might be lower than many but just shoot away

    your hp looks good ... but TQ numbers seem VERY low ... my 95 with 148K miles and 100% stock (even a paper air filter) made 245hp and 275tq ...

    with you having
    "355 stock compression 52mm ported tb/intake With all supporting mods gm847 porrated heads with larger valves( similar to le2) 3k stall 4l80e Dana 60"

    you should be making well over 350tq

    Are u saying the current set up was tuned by sol or is it still running on the rune ur buddy had when he owned it with the beefier set up?

    Man forgot about this thread. It was before Solomon tune.
    I've never ran the car with the Solomon tune. I've been having issue.
    Going to a whole diff set up anyway.
