what is causing this *VIDS*
the stock 10 bolt is a total pile of junk, the clutches and springs in the stock posi unit arent strong enough to hold and thus your single tire fire.
go with the 9 inch, its easier and faster to swap gears in the 9 inch...one of the few good things ford has engineered lol
Even though your 335's are no longer smoking inside the fender, they're still going to smoke for the first 60' ft. of track.
Tried the DR thing, total waste of time and energy. Throw an ET drag stiffwall on there and let it eat.
