    to try something different.....
    big cam, big gears, good intake, and if she hooks she should be a runner. gears are in the mail. hopefully i get them in this weekend and can hit the track sometime the following week for some results for you guys. if clutch holds im gonna try launching at 5K idk how it will turn out tho.. ha

    a friend of mine went 7.82 a couple weeeks ago on a 100 shot. super super conservative tune and it didnt hook to great, so it should pick up a good bit.

    were going to the 1/4 tomorrow if the weather is good and getting it really dialed in. hoping for some 11s on the 100 shot. and bringin some bigger pills!

    Nothin stock about my driveline my trans was built to be equivalent to a tick stage 2 upgraded driveshaft with upgraded u joints and now the rear is built. Only thing factory in my driveline is my stock clutch which will slip way before breaking any of them parts. If anything I toast the clutch which is an excuse to buy a stronger one
