Possible Rear End Upgrades?

[Rev]

Sunshine, are you sure you really need and want a 9"? They are a good bit heavier affecting unsprung weight that affects handling. An 8" should be OK up to about 300 HP. You can get From Currie an 8" 3 rd member with their TSD (Torque Sensing Differential) in any gear ratio you want for $600 or so plus shipping. That's what I did 4 yrs. ago. The TSD is only for occasional hard use according to Currie. If you're planning on lots of abuse, I'd consider a Power Trax locking differential (more$$$). Sounds to me like the 8" ought to be srong enough for your combo.
