A904 Lock up performance build

This is great info and about where I want this car to run to stay in the sportsmen class. Did you just buy a regular 904 stall converter or something special for the lockout tranny?
Turbo Action sells converters with no converter clutch but with the lockup spline count. Call them and talk to Paul Forte. I paid approx 600 for mine S800 tight 3400 flash.
