Violent Take-Off Shudder

I wedged a couple 2x4's between the snubber and the floor board and the shudder is virtually gone. What does this mean if my pinion angle is at -2* relative to the engine centerline?

I'm not a chassis expert, but if you could get 3" of wood blocks in there, then your snubber was for looks if you know what I'm saying. When you use a snubber on a drag car, there is virtually no space when the car is at rest. The rear should rise anyway if all works well. The other thing I would do is double check your angles, maybe get a Mopar chassis book to help, and also, check the clutch because so many other folks said they had experienced those issues as well.
