What the heck is a stall converter?? Does it have something to do with torque converters? Because I have a manual tranny so I thought that I wouldn't have to worry about it, but a lot of things say something about choosing the right stall converter speed. Like buying camshafts and things like that. So do I have to worry about it when things talk about stall converters or since I have a manual I can just look past it???
