i am replacing my torque converter and am wondering if i should just replace it with one like is in there now or get a stall torque converter. what are the pros and cons for each? i have a relatively stock engine. everything is stock except for edelbrock 500 carb, crane 260 cam, roller rockers, hooker headers and .040 bore. it's a 289 v8 engine. so if i were to get a stall converter would 2000 stall speed work for my application? thanks.
