Bdox hit the nail on the head with this one!
When you dump the clutch and the rear tires try to turn forwards, the counter rotational torque twists the axle backwards. This winds up the leaf spring making it sort of "S" shaped. When it is wound as far as it can go, it un-wraps causing downwards force on the tire. This combined with the tire trying to hook up causes the tire (axle) to bounce violently.
Lift blocks exacerbate spring wrap causing broken U-joints and thrown driveshafts due to driveshaft/ pinion yoke misalignment.
What you can do is install a 2" add-a-leaf helper spring to stiffen up your existing springs and chuck the 2" factory spacers that are there now.
The idea is to get your spring as close to the axle as possible and stiffen it up in the process so that the axle wrap is minimized.
I have a 82 F350 4wd with a very healthy PAW (Performance Automotive Warehouse) 460
I had the same problem years back with a 4" lift kit and a built 351 in this truck. Now I still have the 4" kit but I changed the rear springs over to 6" lift springs with no blocks in between the spring and axle, only the angle wedge to pitch the pinion yoke up to properly align the driveshaft.
Axle wrap is now almost non-existant and wheel hop is completely gone.
