68 c10 factory 4.11 ratio?

My 68 i aquired was an unmolested survivor , besides a motor replacement it was an original v8 3 speed truck . I just put a tach in it and according to gps mph at 55mph it's turning around 2600ish rpm with a 31in tire out back . Does that sound right ? I didn't think 1/2 ton trucks got that steep of a ratio . One thing is for sure, I can't go with any smaller tire .
