Torque converter recomendations

[6.2puller]

I have a mildly warmed up TBI 454 in front of a freshly rebuilt TH400 in my V3500 on 37s. Mainly used on the street and towing loads around 10K, sometimes as heavy as 15K. Any recomendations on a torque converter?

Depens on what gears you are running, and what kind of rpms you are normally turning. I would recomend a 2,000-2,5000 stall. But if you cruise under 2,500 alot, you will heat up the trans.Dan

4.10s Turns pretty low RPM alot I would guess. No tach to say for sure.

Then I would go with a 1500-1800 stall to be safe. It will help get you into the power band better for towing.Dan

Any brand recommendations or brands to stay away from?

I do not want to hijack this thread, but what dose stall speed mean? say you have a torque converter with a stall speed of 2500 rpm what dose that mean?

thanks

the stall speed is the speed at which the torque converter stops slipping, similar to when you fully release the clutch on a manual. Any slower RPM allows slipage and creats lots of heat.
