Hahaha. That king ranch was my buddy Robby Bryant. Trucks on 40s with 16 inches, coilovers up front. It has 5.13 gears in it so we figured wed hook to the sled. The differential housing twisted up, snapped the pinion and then spit the driveshaft. Truck ran a best of 13.8x on the strip, pretty consistent 14s.
Ive pulled with my 6.4 a few times, 10" on 40 with stock 3.73s without a problem, other than breakin the pulling hitch at rockville last year. Wish it couldve been out there but its sittin in the garage waitin on me to rebuild the transmission. Burnt up a suncoast pullin somebody out on the beach July 4th.
