I was wondering I have an 2003 GT and the guy I bought the car from said that it a 3.73 gear from the factory, it is a 5 speed. and he changed it to a 4.10. What gear ratios did they come with stock because i thought it was around a 3.55.

If its a manual it comes with 3.27 and autos come with 2.73 I believe.

Stock is a 3.27 ratio.

what speed is your first gear topped out at and what do you cruise at 55 at 5th gear?

3.27 is stock for auto and manual for 99-04. 94-98 had 2.73's auto and manual.

didnt 96-98 5spd have 3.08?

96-98 convertible 5speeds had the 3.08's i believe.
either way theres a calculator around here you to tell you for sure what you have in the rear.
just go out, pick any gear, and write down what your speed and rpm are.
put the speed, rpm and gear into the calculator and it tells what you've got.
thats how we found out my friends "all stock" fox had 4.30's inthe rear

99-04 manuals had 3.27's autos of the same years were supposed to have had 2.73
