Default RPM question for guys with 3:73's and 4:10's

Ok, I bought an 01 gt from a woman that had no idea what mods were on the car. The only thing I am questioning is her saying it had stock gears. From what I have told people they think I have 3:73's or 4:10's. So, can someone with gears tell me exactly what their rpm's are at in 5th gear at 50mph. I am hitting 1500 rpms on the dot at 50mph in 5th. Hope this can help pin point gears.

Yea, with stock gearing at 1500 i was at 55mph but i have the slightly more overdriven t3650. So that might be why.

'cause it's just plain, far from rocket science, math...

How Fast Can I Go in Each Gear?

How Much HP Does it Take to Go How Fast?

Got a late 01 gt so I'm gonna check the vin to see what tranny I have this weekend. if it's the t-45 I have stock gears, if it's the 3650 I have 355's thanks for the chart, build date on the car is 8/01 so it's late 01 thought it would have the 3650
