I watched the video of the Hemi Cuda and noticed the rear chassis rising after staging the car before the launch. Does that mean that the pinion snubber is being used and is adjusted close to the chassis? I was told that Dave was not using the snubber on his Road Runner.
That’s just the engine pushing against the converter. Mine does the same thing but worse.

No. The differential pinion is moving up, trying to flip the diff over backwards, the opposite direction of the wheels trying to rotate forward. (...for every action there is an equal and opposite reaction.). This tries to wrap up the leaf springs into an S, and plants the rear down towards the ground, which lifts the body.
A snubber, once it contacts the floorboard takes advantage of this further and plants the rear even harder and further cause the rear of the body to rise even more.
