Starting with the details
To calculate the right gear scenarios, in the simplest terms, you need to know what your tire diameter is, what the final gear ratio is, what speeds you are trying to reach and what your powerband is. For example, if you want to be at 6500RPM at 130MPH in 4th gear (T5) with a 26″ tire, you may want to look at a 3.90 gear set for your 8.8.
What is powerband?
Simply put, a powerband is the RPM range around peak power output. A lot of modifications (specifically heads/ cam /intake) will increase your engine’s max output but at the cost of the lower-end power.
What others are recommending

In conclusion
If you look at individual modifications and not “the big picture”, you are in for a world of hurt and possible mismatched performance parts that may make your fox body slower than stock.
