Gear ratio

I was wondering if some of you 5-speed guys could tell me what rpm you are running at 70 mph and what gear you have? The hood tag says 3.55 on mine but I think it may not be right. I'm doin 2200 or so-ish at 70

count it out it should take 4.10 spins of the drive line to make one turn of the wheel for a 4.10 gear and so on

Well that pretty much confirmed my theory. I'm not complaining but it's a used truck that was swapped to 4:10… odd. Thanks guys. Good luck clutch shopping Wes
