Stock rear end will hold the torque of that engine, if you were worried about breaking it. Are you looking for more gear for better acceleration?

If so here is a 3.70 gear set for your car. Keep in mind that an OD tranny drops that final ratio down to a 2.59 gear because of the 30% OD. A 4.10 would yield an effective 2.87 ratio.

The 3.70:1 gear set can be founf here:

the bearing and seal kit is sold here:

The 4.10 is offered here:
