Going to need rear tire size ( roll out), and probably torque converter stall speed. I`m sure somebody running that Top Stock combo could help put you in the ball park, without all the numbers, but the data would help

Just to tie things together here, he posted this info in another thread.

"30 x 9 x 15 -94 rol out 6000 stal"

a typical A/SA combo would use a 4.88 or a 5.00 if you can find a set.
