Bakersfield trip last month

Right on. ATF served me well until i built the new motor. I really need a tighter converter but this is kind of a band aid. No one makes turbo 727 converters and so im kinda stuck. I need to change to a turbo 400 so i can readily buy a billet bolt together converter.
I got my turbo one from PTC, its loose but designed for turbos. What brand is your current one?
