Guys, I have never understood the term "stall speed".  Can someone educate me what this means and how it is determined.  I have found a rebuilt FMX for $400 to put behind my 292 in my 55 Tbird.  Given the 55 is aircooled I know I need to run a cooler to the tranny, but can I reuse the torque converter?  I don't plan on getting too crazy with the engine, (I have posted on that in the past).  I plan on using the FOM tail piece since I can then use my original drive shaft.  I know about the gasket issue so will take care of that issue.

Quoted from Rod and Custom Mag: "a torque converter is like a clutch. Imagine when a clutch is fully released, and you get all the power from the engine. That's stall speed. A 2,500 stall speed doesn't mean you need to rev the motor to 2,500 rpm for the vehicle to move." What it does mean in this case is 2,500 rpm is the limit at which the converter will hold back the engine speed if transmission output is prohibited. By disallowing further gain, the increase in engine rpm "stalls." The speed at which stall occurs with a given converter is a function of engine-peak torque."
