I moved to Colorado recently, living in the mountains about 8800 ft elevation. Do I need lockers in one or both axles for winter? Also, I have a crate 350 in my Blazer, not much power at these altitudes. Do I need more cam, or lower gears. The ratios now are 3.73, with an od trans and 33 in tires. Thanks for any help.

I run a locker in the rear for snow. Works great! I leave the front diff open so it steers better.
Try advancing your timing for a little more power. The rule of thumb is 1* advance over base timing for every 2000 ft of elevation over sea level. A good low end cam, intake, headers/exhaust will definatly help.
Do you have TBI or Carb? It makes a difference in tuning/ jetting.
