torque converter upgrade

[pausma]

I have a 91 D350 with a 3 speed automatic and am looking to upgrade my toque converter to a more heavy duty unit. I have approximately 70 hp over stock and I believe my tc is the weakest link in my drive train. What are some good options for my truck? Also, I plan to do the install myself, anything to be aware of?
