there are RPM calculators on the web, that will allow you to figure out what the end result will be before you spend the money to do the 700R4 change. I will tell you that I am a big fan of that conversion, and I would think that if you did a search on this great site you will find several posts from me and others that will help you do it the right way.

RPM calculators will ask;
tire size
MPH
and gear ratio

You will need two of the three to figure out the last. This is very helpful in being satisfied with the end result
