700R4 Torque Converter choice

[bbrriiaann1973]

I have a 70 c10 it has a 383 with trick flow heads and a 700R4 with a stock torque converter. The truck is very sluggish off the line and at low Rpms. If I changed the converter to a higher stall would that help the engine be less sluggish at low rpms?

Other wise truck runs fine, in the beginning I went with a stock torque converter because I didn't want the engine to run hot. As a higher stall converter will run hotter, now I am willing to take that risk.

So to recap 383/700R4 and 3.73 gear posi.

How much of a stall would work best?

Any ideas would be helpful

Thank you
