Default Not sure what gears i have...HELP

Hey guys i bought my stang with some mods on it a couple years ago but i wasnt sure what gears it had when i got it. First gear dominates and it picks up really well and i kind of think it has 4.10's but i really am not sure. Can you guys help me figure out what they are?

Give us an rpm and a speed. That should help us figure it out, provided it's been recalibrated. The true way to find out is pull the gears out. It says it right on em.

cobrastang I just tried that calculations test at 70 in 5th and it is the same rpm calculation on 3:08- 3:23 - 3:27 - 3:55 - and 3:73 wtf? Try it. with 3650 tranny and maybe you can explain cause I'm curious about mine myself now that I have a set of 3:73 in the garage for it.
