    how fast ?

    well my local 1/8th has its last three TNT the next three weekends and im thinking about taking my yukon this weekend and hopefully my car to the last one. just wondering about what you guys think i might run. i kinda want to get a baseline before i really start modding the thing. i will take out third row spare jack all my junk in it ect and ill have 1/2-3/4 regular unleaded in the tank its a 31gal tank. so far only mods are intake and tb bypass. any ideas on a guestimate time? after the new year i plan on lt headers td's high octaine tune e-fans and maybe a small cam and posibly a 100shot.

    GG, for once I think you are right on the money on this one.

    Quick. You and I agree on several things.. This is just not one of them.
    I have seen these stockers run at the track and the timer stops at 18 were I race and they click in sometimes!

    If it is not tuned you should see high 13's if it is tuned you will see high 12's. I tuned my wifes tahoe and it is faster, but not a racetruck by any stretch.

    Ooops Bryan, looks like we might be wrong.

    Let's see the OP's slip.....LOL

    I do a tenth quicker in the 60' and 0.8 quicker in the 1/8th at about 5 MPH more....does that match up?

    Sounds like it...at least I didn't say it would run 18's in the 8th...

    BTW, the OP is right online with my 4.3L V-6 Blazer (206K miles) 'cause it runs 10.6X at 68.
