Mechanically they are different, but they perform the same function, and the same principles apply.

NA car with bigger cam needs a looser converter to flash and get the engine up into it's peak torque range faster for optimal 60ft. They are overall working with a lot less torque and can use the added torque multiplication from a higher stall. PD setups generally work fine with stock converters because they make instant torque...they do not need any more torque multiplication from a converter with a higher STR(Stall Torque Ratio).

I do agree with the aggressive gearing from the A10, even a NA car can face a lot of traction issues. So a larger stall would probably only be utilized at a well prepped track. Another function for higher stall converters is too "soak" up the cam. Big cams need to idle higher and that can cause issues with a tight stall because the engine will want to pull through the brakes if the converter isn't loose enough.

This gets back to the main point for the OP: How much power is he making and what is he doing with the car such that he might need a looser converter? I can definitely see it for a drag car, and you can still get around town with a loose converter.

I sent my 2001 SS LS1 to lingenfelter 20 years ago and one of the mods they made was a looser converter and I think they put a cam in it too.
