I've tried both 3.55 and 3.73's in my Cobra. I think they are both good choices. I prefer
the 3.73's. They won't hurt your top end at
all. The way a stock Mustang is geared you would 600+hp to pull 5th gear to redline. You
can calculate the change in RPM at various
speeds in 5th gear with 3.55,3.73 and 4.10's
and then decide what you think is best for
your application.
