What are the torque converter stall speeds for a 1986 th400 transmission?

Question

i'd like to know because i have an 86 gmc sierra 2500 which i might be getting into and is in the process of getting the 6.2 diesel swapped for a warmed over 454

Answer 1

most stock converters are 1500 rpm.12 inch diameter..no matter what engine it has in front of it they are all the same from the factory..the only difference is a lock up or non lock up.torque converters....

Answer 2

There are not that many different stall speeds for a 400,except if it was behind a 4.3 v-6 the stall would beclose to 2000 rpm the most common converter behind v-8,engines is probably a 1650 or mabe 1750 ,but some early vettes with big blocks and perf engine came with a 2400 rpm stall and are a rare item.
