my 71 K5 is really slow
Hey Everyone .. I'm new here
I bought a 71 K5 CST 4x4 about 6 months ago.. It runs great, has the stock engine, its lifted a bit with 35's
I take it on the freeway and going up even a slight grade, I barely get to 55mph .. and top speed on flat is about 65 ..
I don't need to go super fast, but is the gearing off or? The guy before me used it pretty much for cruising the desert
Thanks for any help or suggestions --

Probably a 3.42, 3.73 or 4.10. Just jack a wheel up after you marked it and the driveshaft it with something easily visible like liquid paper and turn the driveshaft or wheel. Count the revolutions and you have your axle ratio. If you spin your tire once 360 degrees, and your DS turns a bit over 4 times, you have a 4.10 to one ratio for instance.

How to determine what ratio you have without removing the cover
also check your timing and for any vacuum leaks
