    Changin Rear and front Gears I just bought a 1979 K5 Blazer in GREAT condition but it has highway gears under it. I am currently running 2:76 gears i believe in the standard GM 12 bolt rearend. I'm wanting to change the gears out to something a little better for a 4 wheel drive but dont want to completely ruin my gas mileage. Any suggestions. :gunsfiring: :gunsfiring: :help: :yow!:
