I have a 308 in my blazer and hate it. Of course I am running a 29.5" rear tire also but I would at least run a 3:42 or a 3:73. A 3:42 should be a real good gear if your not running that tall a tire. Just my 2 cents and I am no expert. My brother just put 4:56 in his 99 silverado, now what was he thinking? But he is also putting in a t-56 so they won't be that bad.
