You could possibly lower the axle ratio to increase take off performance...

If you have a good converter rebuilder, they will give you a close stall speed to your HP/ trans/ diff count. You could play with diff ratio, but it may affect your highway cruise speed, and rpm.

Try using a lower stall. 1400- 1600. I use the GM33cw from transtar. I like the way they take off . I haven't had any complaints from customers. I have used the lower stall for years
