If you drive a lot and dont have or plan to add tons of power the Ford hd is a nice unit. They work very well. Add a 6l cooler and call it good.
The twisted stg2 is a great tranny. I ran one for a year and then sold my trans/injectors/hpop etc to a nearby friend and he uses that stuff in his worktruck. I had 175/80s and 250/200s in front of it. They dont recommend the 250/200 anymore for the stg2 but when I did it it held fine and shifted with authority. Not rough but it didnt pussyfoit around.
