8" Spragless converter?

Have one of their spragless in my 8 second drag car best move I ever made after braking 2 sprags and ruining the tranny
I had seen and heard of TSI converters before. Just not much mention of them here on fabo. So wasn't sure if its a good move. Currently have an FTI 9.5" 3400-3600 stall converter with 3.91's out back. Motor is a 360 stock stroke and a 292/508 mopar cam. Works well but curious to know if an 8" trans specialties 5000-5400 stall will work ok. Car is not a race car just a fun street bruiser.
