Not enough of a change to make a real difference, IMO. If you're looking to re-gear, I'd consider 4.88's at a minimum. A .50 change in gear ratio will hardly be noticeable.
What are you looking for, better low speed acceleration? Does your 5 speed have an OD? If so, what's the ratio? Do you daily-drive the truck at freeway speeds? Is going with a deeper ratio going to affect the drivability of your truck in a negative way?
What rear axle? Ford 9" axles have a multitude of axle ratios available, so you might be able to find a perfect compromise ratio other than the most common gear ratios.
