    If you can drive it should easily be good for low 12s.

    oh well auto can either be your best friend or biggest enemy depending on how you have it setup.

    On street tires I think you are gonna blow the tires off in first gear when the spray hits which is gonna kill your time if that happens....

    You still have stock gears and converter I assume?

    our track here hooks like a dream now that we have new track owners. I can leave flat footed on motor and not spin at all, once the car sets im going to try and grab the kit as early as possible in 1st.

    Stock 3.08 in rear still? Should go to a 3.73 or something. Will help a good bit.

    Id think you will be close though if you hook...maybe mid 12s at worst

    Looks good. Better 60 and 11s are there. 3.73# could get you there

    yea I need to have my converter re worked to stall around 3500 so I can leave on the kit. gears are a big possibility but the car is at about the top of 3rd gear already, so if I went gears it would deffinantly shift into 4th and kill some time

    You shouldn't.... I was going 121 on 3.73s with a stock tire 26 inch. Is youre converter locking in 3rd?

    A higher stall will help

    I did a 1.64 with 3.73s anda 3800 stall

    I believe converter locks in 3rd, it does normal driving on the street.

    im not sure what top of 3rd gear is, I could probably do a 3.73 with a 28'' tall tire and still be top of third.

    the 1.85 is my best to date.

    did you foot brake the car up into the rpms at all or leave off idle? I bring the car up about 1k rpms and leave, should I try to bring it up higher?

    I footbreak it as high as it would go before breaking the tires loose.

    A 26 inch tire and 3.73 at 6k is like 122 or something....you have 3,27s you said, you should be like 140+ in 3rd dude

    gonna head to the track again after I take some more weight out of the car and get an actual tire under there and will try footbraking it as high as possible to see if it helps
