Torque converter help!
Assuming the below chart is close to actual dyno numbers, which torque converter would you all choose? One with around 2400 stall or one with 3500 stall? Still haven't decided which manufacturer to go with either. Thanks for your help in advance!

If it were only that simple!
You have to provide more info, period!
If this is a mild street use truck, I wouldn't use either, way too much slippage. With all that slippage comes a lot more heat and reduced MPG not to mention sluggish performance is traffic.
Again, you need to let us know how "built" the engine is and what your ultimate use will be.
Just so you know, stock stall is around 14-1600 RPM

IMHO, it is very important that you speak with the torque converter builder (not a saleperson)....there are many factors that effect the actual rpm stall and they have the specific data to determine what you need....you can have a converter that is rated at 10" 1800 & a 12" rated at 1800 as well but the actual stall will be different (by several hundred RPM in the same car) and is based upon the specific design of the converter vs, vehicle weight, gearing, HP/TQ.....and only, and I want to reinforce only the mfg will know what that is.....
Typically in a street car, a stall in the range of 1400-1800 is appropriate, although you can bump this up a few hundred RPM to the low 2000's for a hot street set-up

I spoke with several techs from b&m, tci, and huges. After giving them specs on my engine and truck they told me I needed a converter with a stall that would lockup right before peak torque for street performance. So 2,400 it is. They also explained that staying at stock stall would make my motor "fall on its face" meaning that it would stall wayyyy too early when HP and TQ are too low. Thanks all.
