strong/light weight tranny

[chevzilla396]

i was wondering if there was any type of manual transmissions with all titanium shafts and gears
or if there was any kits for a t56 or tko600 that can withstand 900+ ft lbs of torque? I kno that g-force makes a t56 kit that can hold 900 hp and 800 ft lbs but i want something a little bit tougher.
