Question What gear ratio do I have?

Can anyone tell me an easy way to determine what gears I have short of popping off the covers and counting teeth.
'69 K20, no tach, but it's definately "screamin" at more that 60mph. Do I have 4.56's? If so, anyone with 3.73's want to trade axles? LOL Speed limit on I-90 here is 75mph and I just about get rear ended by 18 wheelers . . . Is it easier and cheaper to change the ring and pinion gears, or to just swap out the whole axle for ones with taller gears?
