    15.21 at 89mph is best to date. but gunning for high 14's next week as my retune for the cam comes with up shift points and raise rev limiter. So be able to pull through third gear at the end. and not shift into 4th right at the end.

    14's shouldn't be a problem if you take those 33" tires off. Go with a bigger wheel.....i would say 18" with a nice performance tire. I think they will grab harder and pull you into the 14's.

    Granted there won't be much weight change...but if you get your pcm tuned for the 18's and tires you should do better.
    Just my

    Ron

    P.S. Then there is always, gettin the Slicks...but that is for the big race fans.

    Traction is not the issue.I am need of more power. I use 4-wheel drive and brake stall it at the line. So pretty much leave the line at full thottle. No wheel spin. Just traction. Granted a stall TC would help, but no one really makes a stall for the allison trans yet. If was a diesel I would be set. Also race weight is around 6100lbs with a 1/4 tank of gas, most everything removed( tailgate, spare tire and jack, etc..). Couple more days!!!

    Not a bad weight for such a big engine. A good set of ASM headers and a cat-back system should get you that power your looking for. But I won't lie, those are not cheap exhaust upgrades. Maybe you should consider a 150 wet shot.
