TONY,
Bob Hokanson has published a great spread sheet on transmission, rear
end, tire size influences. The free reader download of Excel is also
indicated.
This is a great place to check the influence of these selections on
speed and rpm in all gears. Many set-ups are already default entered,
but can be easily changed to your choices:

Be careful, on comparison with other cars, that you know the "offset" of
the wheel, as this has a great influence on wheel rubbing and fit, even
if the diameter and width of the tire and wheel are the same.
