Smile 4.10 vs 3.54

Hi, I am planning to change my gear ratio to lover my rpm. on the high way. Can anyone please tell me how many % I will reduce my rpm changing from 4.10 to 3.54? <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

<o></o>

I have a 1998 F250 7,3d 4X4. Now it runs on 2500 rpm. driving in 80 kmph.<o></o>
