Loose = fast.
Search.
At partial throttle the RPM's run higher than stock. With my 4k stall speed converter I might turn 2,500 rpm to keep up with traffic on a busy road. To pass slowly maybe 3,000.
It HAULS *** when you mash the gas though.

Of course, quickly slipping your engine to a higher rpm range is exactly why bigger/looser torque converters get you down the drag strip so much faster.

a loose converter is a converter with more stall. stall is the rpm at which the car starts to move when you hit the gas a stock c-60 converter (the one in all f-bodies is around 1200) but its just like if you drive a stick and dump the clutch at 4000 instead of 1200 you will accelerate faster. the dissadvantag is that a looser converter is less effecient on the upper rpm range meaning less mph (unless you use lock up then you wory about rpm drop during lock up) so looser not always means faster it depend on combination

1. The stall speed is not the rpm at which the car starts to move when you give it gas. The stall speed is the speed at which the converter will hold the engine speed and not allow further gain, i.e., the point which the converter stops slipping. Your car will start moving well before your converter's stall speed is reached. Can you imagine your engine needing to reach 3500 rpm before you started to move with a 3500 stall converter in your car?
2. The stock F-body converter has a stall speed of 1600 rpm.
3. A higher stall speed may or may not mean a less efficient converter. For example, the Super Yank 3500 is more efficient than the stock converter with an efficiency rating of 97%. Lots of factors besides stall speed go into how efficient a torque converter will be including the tolerances between the pump, turbine, and stator (tighter = more efficient).

It's more like a 4k stall when you go wide open throttle though. That's the beautiful part.
