Just upgrade. There isn't much more you will get out of a re stalled 12". The best one o had would go to 2800 eventually with brakes strong enough to hold it.
You will see a big improvement going to a better/higher stall convertor.
There is no 12" that's gonna do it
So...... I went to the track with my new converter and ran a 12.39@114mph very happy with this ET. Even though I still can't 60 ft under 2sec. Leaves the line harder and surprisingly still hooks good. Just wanted to update everyone who helped me
