If you really want to mess with your options and make comparisons I have an
Excel spreadsheet I made that allows you to compare two trannies against a
stock one. It displays a line chart using RPM vs. MPH so you can visually see
where your gearing (and tire size!) will put you.

> In the near future I will be getting a rebuilt 4-sp trans to go with a 1679
engine in a daily driver. Would there be any benefit to changing the R&P to
3.88 or changing 3rd to something like 1.37? There would be a loss of torque
but the stronger engine may make up for that. Would the lower RPMs at crusing
seriously affect the cooling? I had thought about a 5-sp but they're too
expensive for this budget.
