Best Torque Converter

I used a B&M 069J many years ago too, excellent converter, but they havent been made for years, & the core (early 6cyl falcon 9") is VERY hard to find nowadays, I have used tight 8" done to work similar to the old 069J, around 4800-5200 flash behind a BB, 4200-4500 with a small block, in lots of dual purpose cars.
