gearing

[rwdmayhem]

So I've been trying to figure out what kind of rear end ratio to get my 65 c10. I know some members has stated they're running 3.08 however I have a rather steep incline on the way to work. Even my 2000 monte carlo ss has to stay in 3rd to make it up the hill and it makes about 200hp stock versus my c10's 230 which supposedly make 140hp. I would like to go out and find a T5 but I doubt I could even use 4th or 5th on the hill climb to work. what do you guys think I should do for gearing?
