It's possible to over-gear an engine to the point it can't develop enough torque to pull the vehicle along a level road reliably, and even a slight hill or an attempt to accelerate or pass puts it into a "lugging" situation where more throttle opening doesn't produce any more RPM. Both performance and gas mileage take a big hit at that point. With that rear end you'll be spending a lot of time downshifting, and forget about ever getting the torque converter clutch engaged.
