I'd agree. Find you a 3.42 or 3.73 rear axle, even if it's open, get it, then install a lunchbox locker. Lunchbox will hold up to TPI 350 HP/Torque on relatively stock tires.

I have a major exhaust leak that is causing problems but once that is fixed, it looks like it will run fantastic.

With the exhaust leak, I haven't driven it. Plus I need to dial in a few things like the TPS and TV cable.
