727 and converter

Hello all , new member here . I've been getting much help from this site for a good while and decided to jump in and ask a question.
I am just starting to rework a 73 Duster that my father-in-law bought new. It of course was all /6 . I have a newly built 408 stroker and a new complete Dana 60 from Strange. I am looking for recommendations for a decent 727 trans. and torque converter. I am going to use a 3200-3500 stall for about 80/20% street/race.

Thanks in advance,
Dustaar (duster/aar cuda)
