When I burn out I am getting wheel hop when I shift into 3 gear(manual valve body) 1-2 is smooth, as soon as I get in third it starts hopping. It had HD leaf springs and the stock pinion snubber on the 8.75 any ideas?
 
Get adjustable pinion snubber and set it as close to the floor as you can 1/2" or so, check your pinion angle.
 
What are you burning out in?
Shocks? Gear ratio? Snubber gap?

Even HD springs will wrap with enough power/torque.

Decent shocks can probably help, traction bars more so.
 
Check both the front and rear spring segments. Make sure the front segments are strapped together good and the rear segments are not. This will allow the springs to work as designed and plant the tires harder. How old are the springs? If they are old enough to sag and be worn, that will cause wheel hop as well. Wheel hop in leaf spring cars can almost always be traced to "something" about the springs.
 
If using a snubber, trash it.
clamp every segment in front and remove all clamps in rear segment.
What is the pinion angle ? should be 5-7 degrees nose down
 
It’s a 71 dart 4 door, w/400, 355 gears. Not sure of the pinion angle, it’s a stock housing, I’ll have to check it. It has a stock snubber on it now, not sure how far it is away from the floor, I do have an adjustable one sitting around the shop. The leaf springs were bought new in 2006. Shocks are adjustable I believe they are set at 50/50
 
Stiffer shocks. I had SS springs, low gear 904, very high stall converter and lots of rear gear using Mopar 4-speed drag shocks on my Dart. If traction wasn't ideal, they would wheelhop. Any leaf spring will want to wrap-up and then unwrap. Shocks help control this. The harder a car leaves, the stiffer the shocks need to be. Been using Rancho adjustable rear shocks with great results. I believe Calvert had them relabeled for his set-up.

Unless you want to spin the tires a lot, get better rear tires, so it hooks up instead of spinning endlessly.

I had to fit slapper style bars on my SS Springs to control the spring wrap, but they must be fitted so the front snubber is just touching the bottom of the front spring eye. I even cut the snubber to half its original length to get the bars up higher. The increase in traction was astonishing for such an inexpensive fix plus it eliminated wheel hop on both my Mopars. Both cars have never hooked up harder.
