I went from a "stock low stall tc" to a "stock high stall tc" in a lot of mopar trannys
mopar was good about duel purpose tc and depends on what it was in
thats why some mopar engines "seemed" hotter than others,with basicly the same out put at the flywheel
for example,my 85 318 truck came with a low stall tc
I went to a tranz shop and got a stock high stall tc for a 225-/6 engine
put it behind the 318,(same balance) idles 650 in gear and light throttle it stalls at 1500-1800 rpm and will flash to 2000-2200 rpms when stomped
truck is mucho fun to drive now
in the mopar catalog they are listed as duel purpose and then there is a race converter
this works the same for any combo,a 360 tc will stall higher on a 440 than the stock 440 tc
a hemi tc will not stall as high on a 440
it depends on how much torque you put in to one for the amount of stall that you get
I am no expert but I have swap a lot of tc and trannys,mix matching to get the results I want with out haveing to use after market high $ tc
more to it than you think,IMO
