what would be a good ratio to go with? i'm thinking somewhere in the 5.13 -- 5.38 -- 5.86 range. ive got a bored 350(probably will go with a 454 down the road), sm465, 205. With 24" lift and 44 or 46 I can't see myself doin much more than 55mph. How difficult is it to install gears and locker? Just need the right book and right tools like everything else I bet!
