8 3/4" How Strong?

The Dana power lock sure grips seem to be a little bit stronger than the cone style... I seen a guy running 800 horsepower throw the tires in the air with a 741 case sure grip and got 20 passes out of it before he broke the Caps off... Which by the way is the failure point in 8 and 3/4 rear ends the Caps tend to snap but only if you're running lots of power. ... I've never seen it 8 and 3/4 pinion snap or fail ... Maybe the only exception to this is in the 489 cases without the crush sleeve delete. Remember even the 741 case has a larger pinion than a Ford 9 in in diameter .. my 416 340 running right around or just under 600 horse and I haven't broken any of my 741 cases yet.
