There are a lot of possibilities for the Vibration:
1. base idle and timing need to be set properly
2. your Engine Mounts are too soft and at hard acceleration or high rev take-offs your engine torque's front to back, causing wheel hop due to the engine moving, the tranny moves and your axles with it causing wheel hop
3. you need to check for broken stabilizer links, bushings and balljoints, the axle might also be bent. also check your struts (they might've blown)
4. check your wheel balancing as wheel, if you notice vibration only at high speed.
