What parts are need to make these things handle around 400 hp. I know a torque converter and valve body but is there anything else

pretty much should just buy a BTS...throw it in and go! and never worry about anything again. otherwise, Converter, valvebody, clutches and bands, (id recomend a deeper Mag-hytec Pan)....by the time its all done you could have gotten that BTS for about the same price

Dpends on what kind of milage you have on your truck. A triple disc TC and a upgraded VB (bts or John Woods) would be a good start.

A BTS would be a good move if you have an extra $5k laying around...
