Cons: The price to rebuild is costly. Converters are costly. You have a delayed shift time unless you know what you are doing.

Pros: i dont need a loose converter to 60' since i have the 4:10s and a short 1st gear i get 15mpg avg with a truck that stays 12.7-12.9 afr the whole time. On the highway i get 19-20mpg depending my cruise speed and distance i drive. You always have a sweet spot mph wise for a roll race

Why does your truck stay so rich all the time even at cruise?

Im no tuner either I just know its suppose to be closer to 15 at cruise and at light loads. Mine hovers around high 14s until I really get on it then PE kicks in and drops to mid 12s.
