I got cammed

So guys just picked up my car and i have to say the power is great, but i have a small problem if its a problem. The car is fine at idle normal chop, but once i hit the highway and go above 60 mph the car starts to vibrate hard, i don't know if this is normal since i never added a cam to a car before. Also i did the conversion from l99 to ls3 and added 3.91 gears.

update: Got the car fixed it was the driveshaft like "Litle88" said and once they fixed it car was running better. Also the 3.91 gears makes a big difference just saying.

Thanks guys,

Listen to these guys.

His Rearend not set up correctly? Driveshaft not on right?

Any Susie suspension work done? If so alignment might be in order.
