Wheel hop in REVERSE?

The engine is always tilted down in the back by about 2* so the trans is probably correct. I have never seen the trans at 0*, the engine would have to be straight level. If you look at the intake manifold the carb is always lower in the front this puts it level when in the car. So you want your pinion about 0* so when you accelerate the pinion pushes up to about 1-2* then it should be good.
