Chris,
What you presented is a question that is open to many subjective opinions. It all depends on what you are trying to accomplish.
The first thing to consider is that it is going to have a 5 lug bolt pattern which does not match the front unless you are planning a 5 bolt disc brake conversion. It will also require welding the spring pads and possibly a u-joint change. Wheels will also be required. In addition the gear ratio may not be a good match for your existing engine/transmission combination. If everything is being changed out then it may be a good choice.
If you are going to leave everything else stock and need better highway performance, put in the factory overdrive transmission.
It's cheaper, less work, and no modifications required.
Fred
