Reputable West Coast 727 rebuilder ????

Hi
looking for a someone on the west coast (california) to buy a rebuilt 727 from. I was planning on getting a TCI tranny, but after reading the stickie I decided against that.......
I live in the san francisco bay area and would like to be able to buy the trans from a local reputable shop.
My project is a 69 Dart with a 340. The engine shall hopefully make 400hp.
I will mostly drive it on the street , but might take it to the track to see what it will turn in the 1/4.
Thanks
