Stock or Modified our trucks 02/03 will spank the Hemi's. A friend of mine wanted to race for months and I finally gave in, he took me from the start by a foot and I took him by a truck length length in the next 8 seconds of racing. At the time I only had a single blade THrottle Body/K&N drop-in and Magnaflow Cat-back. He had a chip and Magnaflow only. It's always fun.
