Im the buby cummin un glued was talking about 508hp and 1117 ft lb and no problem yet ben like this for 8 or 9 months now and I rod the hell out if it big input shaft and brass blockers.

I'm on my 3rd tranny, no boosted launches or hard shifts. I've blown 3rd gear into pieces once, 2nd gear twice. Twisted my input shaft like a pretzel once also.

839 1500+ on all factory parts nv4500 except lock nut & Input. It's all in how hard you are on one!

Of course...I do have a couple twisted inputs to show off

I daily drove this truck at almost 700 for 2 years!

exactly, don't beat on it and don't lug it...
