I would go with the 4.10's but if your tires/suspension can't handle the torque, then all you'll do is spin the tires.

As long as your motor has a strong high RPM powerband and can rev strong to 6500 or so, go with the 4.10's Since you have 400 HP this should work out. If your motor noses down after 5,000 rpms, the 4.10's will probably slow you down at the big end, as you will run out of power before the finish line comes.
