Being fooled in 2008 with a garage/shop...we found this today !!

To make this short....in 2008 at 23 years old i had a 360 in my duster with a 727... it blew up at my first summer with the duster, made a deal with a garage and they tried to rebuilt it..yes tried... ** took them 6 attemps and 2 trans cases , took months to have it worked the right way , once it was fixed it ran very good for years until last summer when i offered to buy the car back, wanted to have it inspected and the new transmission place told me that the bands were shot and the kickdown system killed the trans...as i always found that it was shifting too fast or was kinda locking or hitting at a low speed : so long story short : we removed the trans today me and my friend and ....guess what ! It was a 904 lock up with a 2900 non lock up stall ? I was freakin out and even wondering how could this freakin poor little thing could last behind a 410hp / 440 torque engine( 380hp mopar crate ) i have a two 727 with a stock stall or '68 904 non lock up with a 1900/2000 stall with a rvb still dont know what to choose and modify my driveshaft if i go 727 etc , im kinda mad and frustrated because the old trans shop who did the trans is now closed and i will never know why they screwed up and never had a 727 back in it , I honestly cant believe how long a non lock up stall survived in a lock up 904 / yes it has a * 1 inch machined surface @ input shaft*.
