Re: Which Torque Converter for 1991 GTA, 5.7L?

The only way to only way to truly know, would have to been to get a base line before you put the stall in and then go back to the track and run again and see if it slowed you down or not. "Usually" you will pick up some quicker et's. tey say at least a few tenths.
