I have decided to give these converters one more chance, before going with a clutch
Since I can t get a clear answer from anyone, I feel we need to discuss converters a little and maybe we can learn something

I have a 7" converter that we modded over here and got the stallspeed to about where it needs to be, around 7800, but it slips badly downtrack
and only drops about 400 rpm on shifts, gets very hot, speeds around 152 -153, et s 8.9-9.0

borrowed an other 7", 7400 stall, rpm drop OK, 152-153, best et 8.81

tried a 8" of unknown origin, 7400 stall,rpm drop OK, 158.5 and 8.74

What do I try next? I need that 8000 rpm launch without slipping down track
