Okay lets start with this....look at my signature and you will see that our builds are almost the same....I had a Turbo Action 10" convertor in my 340 A904 tranny...no problems....then when I stepped up to the 440 I used them again....oh oh...WTF...the stator in the convertor shot slivers of aluminum in my pan on the very first maiden cruise...another tranny later with same results...hence now I know alot more about trannys and torque convertors....Rick Allison with A&A transmission taught me alot....he also lined me up with a 9 1/2" convertor from Transmission Specialties that is excellent to say the least....I can smoke the tires in second gear with half throttle...it will cost you $200 plus more to go that route but I would do it in a heartbeat.....now I sent my first convertor back to Paul Forte to cut open and see what happened...he will send me another replacement...I will have a complete spare tranny with torque convertor..by the way it stalls at 3000..
