Violent Shaking

This just recently started happening, If I take off from a stop light and gun it....the car seems to "jump" and is very rough and bouncy. Usually the tires would spin but now its got this happening. Everytime it starts to do it I always let off the gas and it stops happening but just wondering what it could be and how I can make it stop happening.

Maybe its your trans mount!

Sounds like it could be wheel hop. If you don't know wheel hop is when your tire under acceleration bounces up and down like if it was a basketball being dribbled. If you have not added any power to the car lately then it could be a shock or one of your rear suspension bushings going bad. If you just did a power mod, fbodys are know to have wheel hop issues and an after market torque arm and lower control arms well help fix the issue. Relocation brackets also help by allow you to create more anti-squat.

I was thinking it was wheel hop as well but wasn't quite sure. I added a cam...but it was atleast 2 months ago so it shouldn't just be affecting it. I also did Koni SA shocks a couple months ago...so don't know if it would be a shock. I will have to put it on our lift and check it out and see if I see anything that looks suspicious

While you have it on a lift, I'd check the motor mounts and trans mount too. I do not think either would cause what your seeing, but it would not hurt to check them out too.
