4.56 is the better choice of the two

In my opinion I would not use the stall it is to tight .We did a similar build about 12 years ago for a friend of mine with a 3000 stall and to much gear and it ran low 8s and high 7s. with a c-4 trans. changed the gear to 4.11 and a 3800 9.5 and went 7.20s later tuning and cam change it went 6.90 all 1/8th mile car and all motor.

Good luck and in my opinion I would put 4.11 or 4.30 gear with 3500 stall to 4000 stall .

So sell both sets of gear and get the correct ones...... or swap someone for the right ones?

What about sending the converter back to get it stalled? cheaper than a new one and it get it right?

If you don't get the converter to leave at about 200 above torque peak, the gear ain't gonna help a bunch.
