If the street manors are good might leave the converter be. It is going to be hard to get the slip race car efficient with that big ole lever you got on the end of it. Just a thought. The tighter converter would widen the shift extencion and lower your trap rpm.
That's exactly what I'm debating over the winter. Normally with an 8" converter and 4.30 gears I expect about 3% slip out of my converter, but with this car having 3.23 gears and a 9.5" converter, I'm wondering if a little slip is helping it..?
It drives great on the street and strip and the trans fluid is always red in color like new. I would not be very happy if I did all the work to remove the converter, pay to have it tightened up, and then the car slows down a tenth or two. Then again it might drive better on the street and it is 80% street driven.
