ok, but let me say this: You can 60 ft much better with your current set up. I had factory stock leafs on a '74 Dart Sport with 275/6015's drag radial. I did low 1.8's 60ft. I did add cheap slapper bars (here come the haters.. LOL). They lifted the back end about 2" when i came out of the hole. the hole car lifted. I also was able to run about 32 psi pressure in the back tires, which will roll better than 20 psi. Car put all the power I had to the ground. If I'd had more power, it would have stuck. You don't have to spend 2000 bucks to hook a car. Not a car that's in the 12's....
